BUFFER CIRCUIT HAVING AN ENHANCED SLEW-RATE AND SOURCE DRIVING CIRCUIT INCLUDING THE SAME

摘要

A buffer circuit is provided. The buffer circuit includes an operational amplifier and a slew-rate compensating circuit. The operational amplifier amplifies an input voltage signal and generates an output voltage signal. The slew-rate compensating circuit generates a compensation current based on a voltage difference between the input voltage signal and the output voltage signal, and provides the compensation current to a load stage of the operational amplifier.
