Switched-Capacitor 2:1 Step-Down Voltage Converter Modulated on 90nm and 45nm

Swati Singh, Uma Nirmal


DC-DC converters are one of the main component of a power management unit. Their main role is to provide a constant, smooth output voltage to power the electronic devices. Switching mode DC-DC converters are critical building blocks in portable devices such as mobile phones, laptop, etc and hence their  efficiency and power are a important issue. This paper describes design techniques to maximize the efficiency of switched-capacitor (SC) DC-DC converters. The measured performance of  switched capacitor converter implemented on tanner EDA tool at 45 nm and 90nm CMOS technology with 2V input voltage to support  efficiency 94-95%

Keywords: DC-DC conversion, switched-capacitor, switching converter
