A high-slew integrator for switched-capacitor circuits

A new method for boosting the slew rate of a switched-capacitor integrator is introduced. The enhanced integrator contains an output booster stage which reduces the settling time by approximately a factor of three over an unboosted integrator. 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 a factor of 40% and the total die area by a factor of 20%.
