Description

Technical Field

[0001] The present invention belongs to the field of millimeter wave and terahertz integrated circuit design, and specifically relates to a millimeter wave and terahertz amplifier design method and related devices based on deep learning. Background Art

[0002] In the sub-terahertz frequency band, the limited gain of CMOS devices has become a key factor restricting the design of CMOS sub-terahertz amplifiers. Due to the high frequency characteristics of the sub-terahertz frequency band, the parasitic parameters inside CMOS devices, such as resistance, capacitance and inductance, have a particularly significant impact on the deterioration of device gain. These parasitic parameters will not only reduce the gain of the device, but also introduce additional phase delay and noise, thus affecting the overall performance of the amplifier.

[0003] At present, the technical means of device physical property analysis and layout optimization are usually used to reduce the influence of parasitic parameters. Through in-depth analysis of the physical properties of CMOS devices, we can understand the source and influencing factors of parasitic parameters, and then reduce the value of parasitic parameters by optimizing the device structure and layout. However, although this method can improve the gain of the device to a certain extent, it is still limited by the physical properties of the device itself, and it is difficult to achieve a significant performance improvement.

[0004] In order to improve the gain performance of CMOS sub-terahertz amplifiers, researchers introduced embedded compensation theory and methods. The embedded compensation network technology introduces additional compensation elements into the network to offset the influence of parasitic parameters, thereby restoring and improving the gain of the device. The patent with the authorization publication number CN114024514B discloses a neutralized amplifier structure with a series lossy embedded network. Under the two-port network composed of a traditional amplifier, a series lossy embedded network is introduced to improve the unidirectional power gain under the preset conditions, and based on this, the Y / Z type LLREN is used to further improve the maximum available gain, so that the power gain of the amplifier is effectively improved. However, since the embedded compensation network technology is based on the network parameter theoretical analysis method, and the embedded network usually adopts a transmission line structure, the solution space is limited. At the same time, the transmission line network parameters are strongly correlated with the operating frequency, resulting in the performance of the embedded compensation network being limited in the sub-terahertz frequency band, making it difficult to achieve the requirements of broadband and high gain at the same time. Summary of the invention

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] like Figure 2 and Figure 3 As shown, this embodiment provides a millimeter wave and terahertz amplifier design method based on deep learning, comprising the following steps: S1, pixelate multiple arbitrary embedded compensation network structures and construct corresponding two-dimensional matrices. Specifically, use the idea of ​​image pixelation to randomly generate 400,000 20×20 two-dimensional matrices for arbitrary embedded compensation network structures using MATLAB.

[0022] S2, inputting the two-dimensional matrix into the network parameter prediction model to obtain the corresponding embedded network S parameters. Specifically, on the PyTorch platform, the two-dimensional matrix and the embedded network S parameters generated by the electromagnetic simulation are used as the input and output of the convolutional neural network, respectively, and the convolutional neural network is trained and verified to obtain the network parameter prediction model, and the function fitting relationship between the embedded network S parameters and the embedded compensation network structure is constructed through the network parameter prediction model.

[0023] The convolutional neural network architecture includes 12 convolutional layers and 5 fully connected layers. Each level of convolutional layer is connected to a normalization layer and an activation layer in sequence. The first four levels of fully connected layers are connected to a normalization layer, an activation layer, and a random dropout layer in sequence. The activation layer uses a Leaky ReLU function to prevent the gradient from disappearing to ensure a good learning effect of the convolutional neural network. The random dropout layer can reduce the possibility of overfitting in the convolutional neural network learning. In this embodiment, the number of channels of each convolutional layer is 102, and the convolution kernel sizes of the first to twelfth convolutional layers are respectively: 16×16, 12×12, 10×10, 6×6, 5×5, 5×5, 4×4, 4×4, 4×4, 3×3, 3×3, 3×3; the neuron data of the first to fifth fully connected layers are respectively 1000, 1000, 800, 800, 120.

[0024] The 20×20 two-dimensional matrix in S1 is input into the above-mentioned CNN, where the first row, first column, eighteenth row and eighteenth column of the two-dimensional matrix represent the excitation port positions respectively, and the CNN output is the embedded network S parameters of the electromagnetic simulation of the embedded compensation network structure represented by the two-dimensional matrix.

[0025] Preferably, in the electromagnetic simulation process, after using a generative adversarial network to use the two-dimensional matrix and the embedded network S parameters as the input and output of the generative adversarial network, a new two-dimensional matrix and a corresponding embedded network S parameter data set are expanded to reduce the time required for data generation, and then on the PyTorch platform, the two-dimensional matrix and the embedded network S parameters are used as the input and output of the convolutional neural network, and the convolutional neural network is trained and verified to obtain a network parameter prediction model. The generative adversarial network can be in the form of a deep convolutional adversarial network (DCGAN), a progressive growing generative adversarial network (PGAN), a bulldozer distance generative adversarial network (WGAN), etc.

[0026] S3, after constructing the relationship between the embedded network S parameters and the amplifier Y parameters, globally optimize the embedded network S parameters to obtain an optimal embedded compensation network structure, and design the amplifier according to the optimal embedded compensation network.

[0027] like Figure 1 As shown, the Y parameter of the amplifier is composed of the Y parameter of the embedded compensation network structure and the Y parameter of the transistor, that is, the following formula (1): (1) In formula (1), is the Y parameter of the amplifier, is the Y parameter of the transistor, is the Y parameter of the embedded compensation network structure.

[0028] The relationship between the embedded network S parameters and the embedded compensation network structure Y parameters is constructed as follows (2): (2) In formula (2), is the identity matrix, is the embedded network S parameter.

[0029] According to equations (1) and (2), the relationship between the embedded network S parameters and the amplifier Y parameters is obtained, namely equation (3): (3) Combined with the relationship between the embedded network S parameters and the amplifier's Y parameters, the embedded network S parameters are globally optimized through a genetic algorithm to obtain the optimal embedded compensation network structure. The genetic algorithm can be replaced by other global optimization algorithms, such as: imperial competition algorithm, particle swarm algorithm, simulated annealing algorithm, greedy algorithm and domain search algorithm.

[0030] like Figure 5 As shown in Figure 2, the specific genetic algorithm optimization process is as follows: S3.1, first initialize the population, randomly generate 2048 two-dimensional matrices as parents through MATLAB described in S1, and use the CNN trained in S2 to predict the embedding network S parameters of the embedding compensation network represented by the 2048 two-dimensional matrices; S3.2, taking the expected S parameters as the target, embedding the mean square error between the network S parameters and the expected S parameters as the cost function, as shown in the following formula:

[0031]

[0032]

[0033] In the above formula, (Cost Function) is the cost function, To embed the network S parameters, is the expected S parameter, It is the function fitting relationship between the embedded network S parameters and the embedded compensation network structure.

[0034] The error between the embedded network S parameters and the expected S parameters is calculated by the above cost function, and the minimum error between the expected S parameters and the embedded network S parameters calculated by the cost function is used as the objective function, among which the two-dimensional matrices corresponding to the 16 minimum errors are selected and directly inherited to the offspring.

[0035] S3.3, randomly select 256 two-dimensional matrices from the parent generation, read the corresponding errors, select the two-dimensional matrices corresponding to the two smallest errors as the parent generation individuals, generate a child generation through crossover, and repeat S3.3 until the number of children generated is equal to the number of parents described in S3.1.

[0036] S3.4, update the population through the offspring generated in S3.3 and the two-dimensional matrix corresponding to the 16 minimum errors in S3.2. The new round of population also includes the offspring generated by the crossover in S3.3 and the two-dimensional matrix corresponding to the 16 minimum errors in S3.2.

[0037] Repeat S3.2~S3.4 until the preset number of iterations reaches 100 times, generate the 100th generation population, and finally select the two-dimensional matrix corresponding to the minimum error as the optimal solution to obtain the optimal embedding compensation network structure.

[0038] Finally, the amplifier is designed according to the optimal embedded compensation network structure, such as Figure 6 As shown, the electromagnetic simulation results show that the method designs a sub-terahertz amplifier with an operating frequency range of 180GHz~220GHz, a gain greater than 1.8dB, good stability, and a total power consumption of about 7.8mA. The electromagnetic simulation results verify that the amplifier design method based on convolutional neural network and genetic algorithm provided in this embodiment can solve the problem that the existing embedded compensation network has limited solution space and is strongly related to the operating frequency, and realizes a broadband and high-gain amplifier.

[0039] The millimeter wave and terahertz amplifier design method based on deep learning provided in the above embodiment has the following advantages: (1) Using the idea of ​​image pixelation, any embedded compensation network structure is pixelated and decomposed. A two-dimensional matrix is ​​used to represent any embedded compensation network structure. Then, a convolutional neural network is used to construct a fitting relationship between the embedded compensation network structure and the embedded network S parameters. The solution space is large. Finally, a broadband and high-gain millimeter-wave and terahertz amplifier can be obtained through genetic algorithm iteration. This method can solve the problem that the solution space of the embedded compensation network is limited and strongly related to the operating frequency, and tap the ability of active devices to provide gain in the sub-terahertz band, so that broadband and high-gain amplifiers can be designed. (2) Using a generative adversarial network to expand the data set formed by the embedded compensation network structure and its corresponding embedded network S parameters can reduce the time required for electromagnetic simulation and improve design efficiency; (3) By modifying the genetic algorithm cost function according to the different requirements of the amplifier, the fitting relationship between the arbitrary pixelated embedded compensation network structure constructed by the convolutional neural network algorithm and the embedded network S parameters can be used to comprehensively generate the optimal embedded compensation network structure that meets the performance requirements. This has the advantages of strong applicability and efficient design.

The convolutional neural network includes n convolutional layers and m fully connected layers, n is the number of convolutional layers, m is the number of fully connected layers, each of the convolutional layers is sequentially connected to a normalization layer and an activation layer, and the first m-1 levels of the fully connected layers are sequentially connected to a normalization layer, an activation layer, and a random inactivation layer, and the activation layer uses a Leaky ReLU function.
