Low-sensitivity bandpass filters using the operational-amplifier pole
Abstract
The single-pole rolloff of the operational amplifier is used to realise 2nd-order bandpass filters with one external capacitor. These filters have low sensitivity to all the circuit parameters and are suitable for high-frequency medium-Q factor operation.
