摘要：
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 141MHz to 603MHz for a 1.2pF capacitive load. This filter has been designed in a TSMC 0.25u digital process with 2.5V power supplies. The filter consumes around 105mW of power with a die area of 0.4 mm2 and exhibits -32dB THD.
