AB  - An analysis of a state variable filter of the kind described by Bonello et al is shown which illustrates the effect the dominant pole in the transfer functions of the operational amplifiers has on stability. Two methods are shown which can substantially null this effect, one of which employs the inherent matching of circuits within an integrated circuit to automatically achieve effective nulling.
