This 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 ω 0 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.
