| dc.description.abstract | This thesis implements a ripple-based constant on-time (RBCOT) buck converter with a fast transient response fabricated in TSMC 0.18 μm CMOS process. The steady-state measurement shows that this chip can regulate output voltage from 0.9V to 1.8V while the input voltage is 3.3V and the output load current is from 0.1A to 1A. The load transient response shows that when the output voltage is 0.9V, the undershoot voltage is 78mV and the overshoot voltage is 126mV. The settling time is 2.8μs for a step-up load and 2.5μs for a step-down load. The chip area is 0.922 mm2. The maximum efficiency is 92.32%. This work improves the traditional inductor current ramp compensation technique. Utilizing an accurate transconductance amplifier to amplify the inductor current to increase the system stability and efficiency. Adopting the negative inductor current feedback to improve the transient response. Through the V2 controlled dual loop structures to eliminate the output dc voltage offset issues. | en |
