Abstract

A buffer circuit includes an inverter and a level-shifter. The inverter receives a first oscillating signal at a first voltage level and generates an inverted version of the first oscillating signal at a second voltage level. The level-shifter receives a second oscillating signal at a third voltage level, which has a phase difference from the first oscillating signal, and the inverted first oscillating signal, and generates a buffer output signal at a fourth voltage level.
