Abstract
An analog buffer with low harmonic distortion and low power supply voltage buffers a signal with wide voltage swing. The lower output voltage swing is increased, by adding a voltage level shifter to the feedback path of a servo. The upper output voltage swing is increased by coupling the output load to Vdd.
