Comparative analysis of two gain- and offset-compensated very large time constant switched-capacitor integrators

A novel gain- and offset-compensated (GOC) very large time constant (VLT) switched-capacitor (SC) integrator is presented and compared with the previously proposed Nagaraj-89 GOC VLT integrator in terms of gain error, phase error and offset voltage error. The effectiveness of the new integrator is demonstrated by designing a 60 Hz notch filter.
