摘　　要：提出了一种硅上液晶(LCoS)灰度控制电路的设计方案,分析了液晶的电光特性,给出了LCoS 256级灰度和参考电压源各部分电路的实现方法。用Cadence环境下的Spectre仿真工具对参考电压源系统进行了仿真,给出了电路的仿真结果,验证了设计的正确性。仿真结果显示,参考电压源的4个输出口能够分时输出8个不同的参考电压,实现了参考电压源输出口的时分多路复用,满足了设计要求。A design scheme of gray scale control circuit of LCoS（Liquid Crystal on Silicon） is proposed, and the electro-optical characteristics of liquid crystal are analyzed. The realizing methods for 256 level gray scale of LCoS and circuits of reference voltage source were given. Spectre in Cadence environment is used to complete the simulation of the reference voltage source system. The simulation results are given, validating the effectiveness of the design. results show that the four output ports of reference voltages in different time and ach are consistent with design requirements. referencing voltage source can ieve time-division multiplexing output eight （TDM）. All mulation different of these
