Abstract :
A new CMOS buffer is introduced. A compensation circuit is used to cancel the output voltage offset resulting from the body effect. The voltage offset cancellation is achieved over all the input range, hence resulting in a highly linear voltage transfer gain, which is independent of process variation. A class AB output stage is used in order to minimize the power consumption and increase the driving capability of the buffer. PSpice simulations for the proposed buffer are given to confirm the theoretical analysis.
