Abstract :
In this paper we consider application-specific frequency compensation of integrated circuit feedback amplifiers through computer-aided analysis and design of closed-loop systems. We employ our symbolic circuit analysis program Analog Insydes to derive transfer functions or poles and zeros of uncompensated amplifiers in closed-loop configuration in analytic form. Then, it will be shown how systematic examination of the resulting symbolic expressions can help to find and evaluate alternative circuit parameter modifications by way of which frequency compensation can be achieved
