Abstract :
A comparator-based buffer is proposed to enhance the driving capability of high-gain amplifiers with switched-capacitor loads. A simple correction scheme using a resistor in the charging path and a correction phase reduces the overshoot of the output voltage. SPECTRE simulations verify the effectiveness of the proposed scheme.
