Abstract :
A 5GHz low-voltage CMOS integer-M frequency divider whose modulus can be varied from 2403 to 2480 for WSN applications is presented in this paper. The divider contains two blocks, a dual-modulus prescaler (DMP), which adopts the structure of the pseudo-differential static D-type flip-flop, and a pulse-swallow counter. The whole frequency divider is designed in 0.18μm CMOS process and the simulation results illustrate that the divider can operate normally over a wide range of 4-6 GHz which consumes 1.89mA at 1 V.
