Novel Cascadable Allpass Filter with a Grounded Capacitor

In this paper, a novel voltage-mode first-order all-pass filter is proposed with a modified current conveyor that has the current gain is equal to 0.5. It employs reduced number of components such as one active component, two resistors and a single grounded capacitor that permits easy implementation with standard CMOS or BiCMOS processes. It is cascadable due to its high input impedance. Simulations are performed to verify the theoretical results.
