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(More)
This paper presents a fully digitally controlled low dropout linear voltage regulator (LDO). It is implemented in a 65 nm low power CMOS process. The input voltage range covers 3 V to 5 V while the output voltage is 2.87 V with a nominal load of 150 mA. The digital controller was implemented using VHDL, automated synthesisand place & route tools. The(More)
