Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] like figure 1 As shown, a passive device complete graph equivalent circuit model based on the Y parameter transfer function matrix is ​​characterized in that: for a passive device with n ports P1, P2, ..., Pn and a ground terminal P0, any There is a sub-circuit C determined by the corresponding transfer function between two different ports Pi, Pj ij , Pi, Pj∈{P0, P1, P2,...,Pn} and Pi≠Pj, thus forming a complete graph network.

[0022] The subcircuit C ij Consists of several submodules M ijk constituted in parallel; and for any Pi, Pj, the sub-circuit C ij has the number of submodules K ij The same, and recorded as K.

[0023] The submodule M ijk It is composed of ideal components such as resistors, inductors, capacitors, or controlled current sources, and is determined by the kth item after the corresponding transfer function is transformed into a partial fra...

Abstract

The invention relates to a passive device complete graph equivalent circuit based on a Y parameter matrix and a construction method, and relates to the field of electronic device modeling. For a passive device with n ports P1, P2,..., Pn and a grounding end P0, a sub-circuit Cij determined by a corresponding transfer function exists between any two different ports Pi and Pj, Pi and Pj belong to {P0, P1, P2,..., Pn}, and Pi is not equal to Pj, so that a complete graph network is formed; and the sub-circuit Cij is formed by connecting a plurality of sub-modules Mijk in parallel. Under the condition that the Y parameter transfer function matrix of the passive device is known, the equivalent circuit of any multi-port passive device is constructed, the model can ignore the influence of other ports on the premise of not losing accuracy, the topological structure of the sub-circuit and the value of each ideal device can be quickly and accurately obtained, and high efficiency and universality are achieved.

Description

technical field [0001] The invention relates to the field of modeling of electronic devices, in particular to a complete graph equivalent circuit of a passive device based on a Y parameter matrix and a construction method. Background technique [0002] With the advancement of CMOS technology, the radio frequency performance of CMOS devices has been continuously improved, which has greatly increased the application of silicon-based radio frequency integrated circuits. As the key to RF circuits such as amplifiers, mixers and voltage-controlled oscillators, passive components usually occupy a large amount of area. [0003] Most passive device simulations use the numerical techniques of electromagnetic (EM) simulation, but they are usually very time-consuming and consume a lot of computer resources, especially memory storage space and CPU time. A simple approach is to use tabular data from measurements or EM simulations, i.e. a table lookup, however, this type of model cannot s...
