Optimum realizations of single‐amplifier networks with zero pole frequency sensitivity and with minimized pole‐Q deviation

Abstract

SUMMARYThis paper discusses realizations of second-order open-circuit voltage transfer functions by single-amplifier active RC networks. These realizations are based on the polynomial decompositions having the property that the sensitivity of wo with respect to the amplifier gain is zero. In addition, the gain-sensitivity product of Q is minimized and the element spread is contained to be within acceptable limits. The realizations are suitable for hybrid IC technology.
