Summary A new state space Class AB synthesis method for the design of square‐root domain filter based on the MOSFET square law is proposed in this study. Those circuits designed by the proposed Class AB systematic synthesis method have the advantages of Class AB circuit structure and translinear circuits. Two alternative design procedures were suggested for designing new circuits. Proposed synthesis technique is applied for designing of a first order all‐pass filter and a third order low‐pass filter. Circuits are simulated in PSpice using 0.35 µm CMOS technology parameters. Time domain and frequency domain analysis of the proposed filters are performed, and simulation results of those are also presented. The simulation results show that the proposed synthesis technique is appropriate for the design of different types of filters and has the advantages of Class AB circuit structure.
