【Abstract】 The encoder of a kind of self-developed fully-integrated 315 MHz RF launching chip is designed.Frequency divider is used to generate strobe signals for either-or data selectors.Through step-by-step selection,the parallel address data are turned into serial data.Verilog HDL language is used for design,Modelsim for simulation,and HeJian 0.18μm CMOS as process technology.The results show that the encoder satisfies the designing requirements when the basic clock frequency is 250 kHz.更多还原
