Second-order switched-capacitor bandpass filter implemented in GaAs
Abstract
A GaAs second-order switched-capacitor bandpass filter has been fabricated. Operation with clock frequencies up to 100 MHz and center frequencies up to 4 MHz has been achieved, with an insertion loss of between 3 dB and 15 dB and a center frequency accuracy of 90-98 percent.
