摘要

将描述一种CMOS模拟信号处理器，该处理器使用数字控制开关时序而不是电容阵列来实现滤波器拓扑和传递函数的可编程性。一个5μm CMOS测试电路已经证明了在±5V电源下80dB动态范围和±3V信号摆幅的有效性。

Analog CMOS filter with full digital programmability

A CMOS analog signal processor using digitally-controlled switch timing rather than capacitor arrays to achieve programmability of both filter topology and transfer functions, will be described. A 5μm CMOS test circuit has demonstrated availability of a dynamic range of 80dB and and ± 3V signal swing at ± 5V power supply.
