Dt. Comer et al., A HIGH-FREQUENCY INTEGRABLE BANDPASS FILTER CONFIGURATION, IEEE transactions on circuits and systems. 2, Analog and digital signal processing, 44(10), 1997, pp. 856-861
Inductorless bandpass filters have in the past been realized using all
-pass circuits based on op amps, This work replaces the op amps with i
ntegrable 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 reduc
e the sensitivity of Q with respect to temperature is reported.
