A CMOS DCCII with a Grounded Capacitor Based Cascadable All-Pass Filter Application

The differential current conveyor (DCCII) is a versatile current-mode active element, which has a current differencing capability. In this study, a new CMOS DCCII implementation is introduced. As an application example, a novel voltage-mode (VM) first-order all-pass filter (APF) is presented. The proposed VM APF employs two resistors, grounded capacitor and has high-input impedance for cascadability. Simulation and experimental results are given to verify the operation of the circuit.
