Abstract:
Recently, switched capacitor DC/DC converters are extensively used in
portable electronic devices because they feature many advantages, such as high
efficiency, small package, low quiescent current, minimal external components and
low cost.
In this thesis, two step-down switched capacitor DC/DC converters are
designed. One has the fixed output options 1.5V, 1.8V and 2.0V. The other one has the
output 1.2V. These two converters are implemented in 0.5μm CMOS process through
National Semiconductor Corporation. The design is verified by the circuit-level
simulations, and design issues are discussed.
