The first proposed converter of this thesis is a fast-transient-response dead-beat-controlled buck converter with active pseudo current-sensing techniques. The dead-beat-controlled buck converter uses active pseudo current-sensing circuit and dynamic-slope compensation technique. This proposed converter has advantages of high stability and fast transient response. The proposed buck converter has been fabricated with TSMC 0.35μm 3.3V CMOS 2P4M technology, switching frequency is 1MHz and the chip area is 1.5 mm  1.5 mm. The experimental results show that the proposed converters output voltage rang is from 0.8V to 2.5V, the maximum output current is 600mA, the best transient response is 2μs, and peak power efficiency is 89% under 2.5V output voltage and 200mA load current
