Abstract
This paper presents a new current-mode first-order allpass filter employing only one current-controlled current differencing transconductance amplifier, one grounded capacitor and one grounded resistor. The use of grounded capacitor makes the circuit more suitable for integrated circuit implementation. The circuit also possesses high output impedance which enables easy cascading in the current-mode circuits. Simulation results are given to verify the presented theory.
