Abstract:
A calibration method for adjusting an offset voltage of a unit is proposed. The unit, capable of operating in a calibration mode or a normal mode, includes a first input terminal, a second input terminal and an output terminal. The calibration method includes: operating the unit in a calibration mode; providing a programmable voltage to the first input terminal; providing a constant voltage to the second input terminal; adjusting the programmable voltage monotonously when an output status of the output terminal is not changed; latching the programmable voltage when the output status toggles; and operating the unit in a normal mode after the output status toggles.
