Abstract :
The high-frequency operation of MOSFET-C continuoustime filters is investigated. The degradation of performance of integrators due to the effects of op-amp finite gain-bandwidth product and the distributed capacitance of the MOS transistor is characterized. A solution to minimize these effects is presented and evaluated for practical designs. Op-amp requirements for good linearity performance at high frequencies are derived. The analyses and techniques shown are verified with computer simulation and demonstrated with an experimental chip.
