Design and performance of a fully integrated bipolar 10.7-MHz analog bandpass filter

Design and experimental evaluation of a sixth-order fully integrated continuous-time 10.7-MHz bandpass filter are presented. Circuit performance is stabilized through on-chip tuning by a dual-loop master-slave control scheme that locks center frequency and bandwidth to an external reference signal. Difficulties in design and performance are discussed and corrections suggested where appropriate.
