Two different realizations are given for synthesizing a second order nonminimum phase transfer function. The first circuit uses a single operational amplifier and a passive RC bandpass building block and has the advantage of being always stable. The second configuration uses two operational amplifiers to activate a symmetrical twin T , and has the advantage of providing a unity gain factor. Sensitivities to all circuit components and the frequency limitation equations for both networks are given.
