Abstract :
A mixed-signal approach for tuning the bandwidth of some continuous-time low-pass filters is presented. The tuning loop uses circuits that exist in many mixed-signal ICs. Simulation results are presented for a number of filters, and measured results are presented for tuning second-order and fourth-order Butterworth filters
