ABSTRACT:
A level shifter for a gate driver has a driving transistor, a reset transistor, a charge/discharge circuit, a threshold voltage detector, and a memory capacitor. An initial threshold voltage of the driving transistor is detected by the threshold voltage detector, and then memorized in the memory capacitor. The charge/discharge circuit charges or discharges the capacitor, and receives a control signal to actuate the level shifter. The reset transistor receives an output signal of a next stage level shifter as a reset signal, so as to restore the initial status of the level shifter. In this way, the driving current output from the level shifter is irrelevant to the threshold voltage of the driving transistor.
