Abstract
A configuration for realising a 2nd-order bandpass filter based on the single-pole roll-off characteristics of the operational amplifier with a single grounded external capacitor is presented. The filter has low sensitivity to all the circuit parameters. Experimental results verify its suitability in high-frequency applications with moderately high selectivity. Independent control of centre frequency, frequency selectivity and midband gain is possible.
