Title: Reduction of the gain errors in finite gain insensitive switched-capacitor integrator pair
Keywords: Filters, switched-capacitor integrators, operational amplifi

Abstract: The gain errors of multi-input Nagaraj-86 and Ki-89 switched-capacitor integrators are minimized by modifying the values of the integrating capacitances C2. Analytical expressions for the prewarped values C2p and for the corresponding gain and phase errors are obtained. The variation of the finite amplifier dc gain A from its nominal value A0 is taken into account. The effectiveness of this prewarping technique is demonstrated by designing a 50Hz notch biquad.
