Abstract :
A CMOS switched capacitor charge pump power supply regulation circuit that combines the reference and regulation blocks into a single block is presented. The switched capacitor topology uses a single PN junction and allows for inputs and outputs less than 1V. The topology was fabricated in Ail Semiconductor´s 0.5 mum C5 process and was used to create a 3.2V supply for an ASIC from an input that ranged from 1.8 to 3.5V
