Abstract :
A new low-power level-up shifter circuit is presented. This circuit produces a digital output signal in the 0-300 V range from a digital input signal in the 0-5 V range. The proposed circuit reduces power through two key features: dynamic charge control reduces the power dissipated in the level-up stage, and a "break before make" logic reduces the short-circuit power of the output stage. Detailed design methodology and optimized circuits for different voltage ranges are described in this paper. This circuit is designed under DALSA semiconductor\´s 0.8 μm 5 V/HV CMOS/DMOS technology. Simulation results validate its operation and performance.
