Abstract

In this paper, high voltage (HV) tolerant level-shifters with combinational functionality are proposed based on differential cascode voltage switch logic (DCVSL). These level-shifters are tolerant to supply voltages higher than the process limit for individual CMOS transistors. The proposed HV DCVSL level shifters are particularly useful when it is mandatory to ensure a specific behavior during out of the normal mode periods (power up; power down; reset; etc.). These high voltage tolerant logic circuits were used in the power block of buck converter designed in a standard 3.3 V, 0.13 mum CMOS process, powered by an input voltage range from 2.7 V to 4.2 V.
