Abstract
A programmable active frequency-selective circuit includes a first capacitor having a fixed value and a second capacitor coupled in parallel to the first capacitor and having a plurality of switchable capacitors connected in parallel to each other. The programmable active frequency-selective circuit further includes a plurality of switches each being associated with one of the switchable capacitors, and a control port coupled to the switches. The capacitors may be varied to account for processing variations that occur during manufacturing of the programmable active frequency-selective circuit. The capacitors values may also be varied to change the bandwidth and/or gain of the programmable active frequency-selective circuit.
