High-efficiency, 6.6–29 V pulse driver using charge redistribution

Fully integrated high-voltage pulse driver with low voltage supplies and low voltage switching signals is described. Using charge redistribution for the output drive significantly reduces switching losses in the load capacitors even with the high-voltage output swing. The proposed circuit implemente...

Description
Summary:Fully integrated high-voltage pulse driver with low voltage supplies and low voltage switching signals is described. Using charge redistribution for the output drive significantly reduces switching losses in the load capacitors even with the high-voltage output swing. The proposed circuit implemented with 0.18 µm HV LDMOS technology achieves 24–55% efficiency improvement for 20 k–1 MHz 29 V pulse generation with 1.2 and 3.3 V supply voltage.
