摘　　要：提出一种通过引入多值求和信号指导设计二值神经元MOS电路的方法.对每个神经元MOS管的逻辑功能均采用传输开关运算予以表示.在此基础上设计了实现常用二变量逻辑函数的神经元MOS电路和全加器等电路.采用所提出的方法综合得到的电路结构十分简单,而且很容易确定各耦合电容之间的取值比例.设计结果同时表明,利用浮栅电压信号易于实现求和的优点,通过引入求和辅助变量可显著简化对电路的综合过程.采用TSMC0.35μm双层多晶硅CMOS工艺参数的HSPICE模拟结果验证了所提出设计方案的正确性.A design method for binary neuron MOS circuits employing a summation signal with multiple values is presented. The logical relation of each neuron MOS transistor is formulated using the transmission operation in order to make effective and practical use of the circuits. Using the proposed method,some neuron MOS circuits realizing two-variable common functions and a full adder are designed, and the ratio of. the coupling capacitance in each circuit can be calculated conveniently. All the proposed circuits have very simple configurations. Furthermore, the synthesis procedures can be simplified significantly since the voltage signals are added easily by means of floating gates in the neuron MOS transistors. The effectiveness of the proposed approach is validated by HSPICE simulation using TSMC 0.35μm double-polysilicon CMOS technology.
