Design of elliptic function filters using a double-layer RC distributed-active circuit

An active double-layer
RC
distributed circuit is analyzed. Design charts for realizing a second-order transfer function with real-frequency zeros and a pair of complex-conjugate poles are given using the dominant-pole approach. A fifth-order Cauer-Chebyshev-(CC) type low-pass filter with equiripple passband and stopband characteristics is realized using these charts.
