Embodiment 1
[0051] Such as figure 1 , figure 2 and image 3 As shown, the present invention first introduces based on an adjustable homojunction field effect device, which includes an insulating layer 3, a metal electrode layer, a channel material layer 2 and a substrate insulating material 1; the metal electrode layer includes a drain electrode layer 41, a source electrode layer 42, gate electrode layer A43 and gate electrode layer B44.
[0052] The gate electrode layer A43 and the gate electrode layer B42 are prepared side by side on the substrate insulating material 1 , and there is a gap between them to ensure that the gate electrode layer A43 and the gate electrode layer B44 cannot be conducted. The insulating layer 3 is laid on the gate electrode layer A43 and the gate electrode layer B42. The channel material layer 2 is laid on the overlapping areas of the gate electrode layer A43 and the gate electrode layer B44 and the insulating layer 3 to ensure that the channel material la...

The invention discloses a unit circuit and a multifunctional logic circuit based on an adjustable homojunction field effect device. The corresponding design scheme includes four steps: the structural construction of the adjustable homojunction device, the multifunctional electrical circuit of the adjustable homojunction device Operation realization, design of basic logic unit circuit and cascaded unit logic circuit realize complex logic function; the present invention first designs the adjustable homojunction device based on bipolar field effect characteristic material; then introduces source-drain voltage in this device As an additional control signal, further, by cascading three reconfigurable logic units, a multifunctional logic circuit with the logic functions of performing a full adder and a subtractor has been designed, and the logic unit designed in the present invention Circuits have the ability to perform reconfigurable logic functions. The logic circuit constructed by cascaded unit circuits can not only perform logic functions such as full adder and subtractor at the same time, but also requires significantly less transistor resources and occupied area than traditional CMOS technology.
Description
technical field [0001] The invention relates to the field of semiconductor materials and devices, in particular to a unit circuit based on an adjustable homojunction field effect device, and a multifunctional logic circuit, and a logic circuit of an adder and a subtractor obtained on the basis of the unit circuit. Background technique [0002] With the rise of new electronic application industries such as artificial intelligence, Internet of Things, and implantable medical care, multifunctional logic circuits with emerging requirements such as low power consumption, flexibility, and biocompatibility have gradually become a research hotspot. Traditional silicon-based logic circuits are difficult to meet such diverse application requirements. On the one hand, silicon-based devices have a single function, and building a multi-functional logic circuit requires a large amount of transistor resources, which will increase the power consumption of the circuit; on the other hand, sili...
