Abstract
One of the limiting factors in the performance of high-p and high-Qp active filters is the finite frequency-dependent gain characteristics of operational amplifiers (op-amps). Investigated here is a simple compensation scheme to reduce the sensitivity of the performance of a switched-capacitor biquad to the finite gain-bandwidth product of the op-amps. Theoretical and experience results show that the scheme is very useful. © 1983 IEEE
