A high-voltage floating level shifter for a multi-stage charge-pump in a standard 1.8 V/3.3 V CMOS process
This paper proposes a high-voltage floating level shifter with a periodically-refreshed charge pump topology. Designed and fabricated in a standard 1.8 V/3.3 V CMOS process, the circuit can withstand shifting voltages from 3 V to 8.5 V with a delay response of 1.8 ns and occupies 0.008 mm2. The prop...

| Sumario: | This paper proposes a high-voltage floating level shifter with a periodically-refreshed charge pump topology. Designed and fabricated in a standard 1.8 V/3.3 V CMOS process, the circuit can withstand shifting voltages from 3 V to 8.5 V with a delay response of 1.8 ns and occupies 0.008 mm2. The proposed circuit has been used in a multi-stage charge pump for programming its voltage conversion ratio. Experimental results show that the level shifters successfully enable/disable the stages of the charge pump, thus modifying its output voltage between 5.35 V and 12.4 V for an output current of 3 mA. |
