Abstract
Inductorless bandpass filters have in the past been realized using all-pass circuits based on op amps. This work replaces the op amps with integrable fixed gain amplifiers to create the bandpass filter. Values of Q exceeding 100 with resonant frequencies approaching 50 MHz can be achieved with an integrated circuit implementation. A method to reduce the sensitivity of Q with respect to temperature is reported
