AMPLIFIER SLEW RATE AND FREQUENCY DEPENDENT GAIN EFFECTS IN SWITCHED-CAPACITOR CIRCUITS

Abstract

The transient behaviour ofthe MOS SC integrators containing a two-stage pole-splitting compensated op amp is analyzed. A nonlinear two-pole op amp model is used in the analysis. Analytical expressions for the SC integrator response and settling time are derived. A design example is given where these results are used to minimize the integrator settling time.
