| Abstract: | This paper presents the design of multi-mode divider for frequency synthesizer.The whole circuit is implemented with the SMIC 65nm technology and is operated at 1.2V DC voltage.The divider consists of nine 2/3 dual-modulus dividers which is implemented with source-coupled logic（SCL）structure and some other logical cells.Simulation results show that when operated at differential sinusoidal wave with the vpp voltage is up to 400mV and frequency range is between 600MHz to 4GHz,the divider can realize the 128 to 1023 moulus divider. |
