Abstract :
Five integrator structures for IC filters are evaluated, i.e., the Gm-C integrator; the Gm-C-Opamp integrator; the Gm-C-OTA integrator; the MOSFET-C-Opamp integrator; and the MOSFET-C-OTA integrator. The advantages and disadvantages of each are presented based on several criteria. The main results of the comparison are provided in tabular form
