ABSTRACT:
An offset cancellation circuit includes a sense amplifier configured to receive an input signal and offset voltages and to generate an output signal. A compensation voltage generation section is configured to be inputted with the output signal, and the compensation voltage generation section increases or decreases compensation voltages until the voltage level of the output signal reaches a target voltage level. The voltage level of the compensation voltages is maintained and a control signal is enabled when the voltage level of the output signal reaches the target voltage level. A control loading section is configured to provide the compensation voltages as the offset voltages or maintains the current level of the offset voltages, according to the control signal.
