Cascadable Current‐Mode First‐Order All‐Pass Filter Based on Minimal Components

Abstract

A novel current‐mode first‐order all‐pass filter with low input and high output impedance feature is presented. The circuit realization employs a single dual‐X‐second‐generation current conveyor, one grounded capacitor, and one grounded resistor, which is a minimum component realization. The theoretical results are verified using PSPICE simulation program with TSMC 0.35 μ m CMOS process parameters.
