Abstract :
This paper presents two fast level shifters with low power consumption used for controlling the output stage of 5 V DC-DC buck converters. The propagation delays of the level shifters in nominal cases are lower than 0.61 ns, which allows controlling the power switches very accurately. The level shifters are very robust against power supply ringing and are evaluated in a DC-DC buck converter test chip in a 65 nm CMOS technology.
