Low Power Switched Capacitor DC-DC Converters for Low Power Transceiver Applications

TL;DRAbstract

DC-DC converters, also known as switching voltage regulators, are one of the main components of a power management unit. Their main role is to provide a constant, smooth output voltage to power the electronic devices. Recent miniaturi-zation trend of electronics circuitry has led to the need for smaller and high-efficient DC-DC converters in current and future applications.

\nThis thesis presents a Switched Capacitor (SC) based DC-DC converter, which can directly operate at input voltage of 4.2V on 45nm CMOS process. Currently, most of the DC-DC converters on 45nm are not able to operate at such high volt-ages. Moreover, SC architecture has resulted in smaller size of converter com-pared with LC type DC-DC converters. 
\n
\nThe design uses three SC topologies, which include two novel SC topologies of 2/5 and 2/7. Devices break down conditions have been overcome by implement-ing some of the MOS switches in cascoded structures. The converter structure uses eight phase
