Abstract:
A switched capacitor low-pass filter. The filter includes a plurality of switched capacitors, and a plurality of resistors. The resistors increase the slope of the roll-off of the filter, reduce DC gain variations across corners, and minimize the frequency variation across corners. In some embodiments, the clock signal used to control the switched capacitor filters has a duty cycle differing from 50%, to improve the frequency response of the filter.
