Design Of The Multi-modules IP Cores For PWM Power Control ICs

Switch power system is widely used in different fields. With the rapid development of VLSI and SOC technology, it is very urgent and significant to construct and perfect the Power Control ICs library of our own Intellectual Property step by step by the way of developing and accumulating the CMOS anolog IP cores .In the thesis, some of the most important functional modules of the PWM Power Control ICs are designed and simulated, including error amplifier, voltage reference, voltage regulator, comparator, and oscillator. The topologies, schematics and layouts of some circuits are introduced and developed. Although the structures of these modules are simple, they can work properly and efficiently in a wide range of ambient temperatures and supply voltage variations.The multi-modules IP cores design is only the beginning of completing the IP series, further more there are many works of constructing the anology IP library. The thesis is considered as the basis of further development of PWM Power Control ICs and various SoC power management modules.
