A high frequency CMOS 4th order digitally programmable bandpass filter

Midwest Symposium on Circuits and Systems, 2000

A high frequency fourth order CMOS continuous time Band-pass filter with programmable bandwidth and center frequency is presented in this paper. Simulations show that the center frequency can be tuned from 141 MHz to 603 MHz for a 1.2 pF capacitive load. This filter has been designed in a TSMC 0.25 u digital process with 2.5 V power supplies.
