碩士 === 國立成功大學 === 電機工程學系碩博士班 === 98 === This paper proposes an all-digital PLL-based digitally controlled dc-dc converter, the main features is to contain the adjustable digital pulse width modulation and low-power windows-based and TIQ-based flash A/D circuit. The advantage of converter is that can accurately calibrate its operating frequency and have all-digital circuit synthesis, low area, low power consumption. By the GUI design assistance software, this paper proposes a top-down IC design flow for digitally controlled DC-DC converter, reduce design time and complexity. Finally this paper verify the circuit function with the FPGA platform and use TSMC 0.18?m 1P6M 3.3V CMOS process to achieve a complete digitally controlled DC-DC converter circuit architecture.
