The Study, Based On High-speed Dsp Circuit Design Methods

At present, with the research on the theory of the high-speed circuit developing gradually, each kind of concrete product which designed in kinds of applied domain is changing people's life unceasingly and promoting the advance in technology under its correlation to the instruction of the theory. DSP (digital signal processor) mainly faces to massively high-speed and high-density operation. It widely applies in the domain of correspondence, aviation, radar, portable appliance and computer and so on. Now the operating speed of the lowest-end product of DSP processor can also arrive at the speed of 100MHz. Kinds of circuit designed by using this processor have the high-speed circuit's characteristic.Through the control theory and control engineering's specialized characteristic and the DSP-processor technology unifying, this paper hopes to research the theory about digital power source based on DSP. It also faces to the domain of present power source and the newest research direction. At the same time, the research on digital power source also takes use of the fuzzy PID technology in the intelligent control theory.For each module, including the power source module, the digital filter, the fuzzy PID module, PWM (pulse duration modulation) and so on, this paper uses tools like MATLAB, SPICE and so on to create the theoretical model and simulate them. Then utilizing DSP to summary some digital power source's essential method and some theory about high-speed circuit's design.
