Abstract

A self-adaptive pulse generator featuring with short pulse width to realize lower power consumption and higher reliability of high voltage gate driver IC is proposed. Under the control of the feedback signal from the output of the high voltage level shifter, the pulse width of the input narrow pulse can be decreased adaptively without affecting the normal operating function. The proposed self-adaptive pulse generator is implemented in 100 V BCD process. Measured results show that the pulse width reduced from 211.6 to 108.3 ns, the high side operating current decreased from 175.54 to 120.53 µA at 25 °C when operations at 100 kHz, and the pulse width tend to be stable as temperature changes.
