Abstract
A new method for improving the slew rate of a switched-capacitor integrator is introduced. A booster circuit is used to measure the integrator input voltage and then inject a proportionate amount of charge at the integrator output. The boosted integrator significantly reduces the settling time due to amplifier slewing. In addition, the booster has no adverse effect on the noise and stability performance of the integrator. The booster stage increases the total static integrator power by 36% and the total die area by 22%
