The first part of this thesis is a flying-capacitor buck-boost converter with wide output range has been proposed to improve efficiency of conventional switched-capacitor converter. The proposed converter has the properties of fast response and the non-pulsating output current, which can reduce both of output voltage ripple and current stress requirement of the output capacitor. The proposed structure utilized pulse-width-modulation technique. The proposed converter can supply an output voltage with wide range which is from 1.0V to 4.5V in high accuracy when supply voltage is 3.3V. The max switching frequency of the proposed converter is 1 MHz. Experimental results proved that the proposed scheme improves the power efficiency up to 90%. The proposed buck-boost converter has been fabricated with TSMC 0.35-μm CMOS 2P4M process, the total chip area is 2.308 × 2.24 mm2 (with PADs).
The second part of this thesis introduces the design of fast transient response flying-capacitor buck-boost converter with wide output range utilizing pseudo-current mode techniques. The proposed structure utilized pseudo-current mode technique to achieve fast transient response when load current changes between heavy load and light load. The switching frequency of the proposed buck-boost converter is 1 MHz for supply voltage is 3.3V and output range is from 1.0V to 4.5V. Experimental results prove that the proposed scheme improves the transient response is within 2 μs and the power efficiency up to 89.66%. The proposed buck-boost converter has been fabricated with TSMC 0.35-μm CMOS 2P4M process, the total chip area is about 1.5 × 1.5 mm2 (with PADs).
