碩士 === 大葉大學 === 資訊工程學系碩士班 === 95 === According to the progress of fabrication, supply voltage of system is descended and the power consumption is also decreased in theory. But more and more transistors can be fabricated on a signal chip, so power consumption is larger. Recently, most of devices especially portable systems are expanded to economical energy because of maximizing the whole run time. The circuits of different kinds of functions in the system usually have demand for different supply voltages. Due to cost, the system can’t support different supply voltage to each function. As a result, a good power management is needed for system. Our research goal is to convert fixed supply voltage to different DC levels which the functions need. This thesis investigates the design for pulse width modulation of system based on fabrication of TSMC 0.35um 2P4M Mixed-Signal CMOS technology. It provides a viewpoint of simulation to synthesize PWM and completes the tapeout of design through CIC.
