MOS开关电容广泛应用于数据动态放大器、积分器、均衡器,滤波器、解调器、振荡器、PCM编译码器、多路复用运算等电路,为模拟电路大规模集成,开拓了广阔天地。 MOS开关电容电路将连续信号离散化处理,工作按电荷在电容上积累、传递、重新分配。电路中变量采用电荷、电压。它能分时操作程控。主要参数依赖于电容之比,故精度高,稳定性好。 MOS switch capacitors are widely used in data dynamic amplifiers, integrators, equalizers, filters, demodulators, oscillators, PCM codecs, multiplexing operations and other circuits, large-scale integration of analog circuits, open up a vast world . MOS switch capacitor circuit will be continuous signal discretization, work by charge in the capacitor accumulation, transfer, re-distribution. Circuit using variables of charge, voltage. It can be time-controlled operation. The main parameters rely on the capacitance ratio, so the high precision, good stability.
