Abstract :
A mixed-signal approach for tuning the bandwidth of continuous-time low-pass filters is presented. The tuning loop uses common circuit blocks (a data converter and digital filters). Simulation results are presented for a number of filters, and measured results are presented for tuning second-order and fourth-order filters.
