Abstract
A comparator-based buffer method and system enhance the driving capability of high-gain amplifiers with switched-capacitor loads. It includes a current source, a comparator, switches, sampling capacitor and overshoot correction resistor. A correction solution using a resistor in the charging path and a correction phase reduces the overshoot of the output voltage while constraining power consumption and minimizing components. Spectre® simulations verify the effectiveness of the invention.
