Abstract
A method of driving the effects caused by finite input impedance and n onzero output impedance of functional building blocks into a frequency shift of transfer characteristics is proposed. The method is quite si mple and systematic. The input and output impedances can have arbitrar y Values under a simple condition which meets the monolithic integrati on of circuits. The effects of non ideal input and output impedances a re converted to a change of integrator gain leading to a simple freque ncy shift of circuits. The frequency shift can easily be adjusted by c onventional methods. A typical example shows a remarkable effect of th e method.
