Abstract :
A simple generation and synthesis method of a second-order allpass function with complex poles and zeros is presented. Networks are realised with only one operational amplifier and simple RC one-ports. The effect of the limited gain and passband of the amplifier on the frequency and Q-factor of the poles is also discussed.
