Phase lock loop is fundamental building block of modern communication system. Phase lock loop are typically used to provide local oscillator function in radio receiver or transmitter. The design methodology and test result of charge pump structure for phase lock loop application are presented. The structure is composed of two charge / discharge block. This paper provides study of various charge pump and discuss the technologies that is used to design charge pump.
