Abstract
The realization of nonminimum-phase allpass filters using a current feedback amplifier (CFA) device is proposed. A simple circuit topology suitable for first and second order functions is presented. With nonideal CFA the pertinent expressions are slightly altered owing to finite port tracking errors (epsi) of the device. The modified design equations have been derived, and it is seen that the realizations are practically active-insensitive. Test results in support of theoretical analysis are presented.
