SENSITIVITY CONSIDERATIONS IN ACTIVE NETWORK SYNTHESIS

Abstract : This report is concerned with the problem of realization of active RC networks, utilizing practical transistor amplifiers, with minimum sensitivity of the transfer function or poles to variations in transistor parameters, in particular to the most variable of the parameters. Two synthesis techniques are considered and realizability conditions are given for single-stage and two- stage realizations. It is shown that the sensitivity of the poles to the variation of transistor alpha can be made as small as desired.
