چکیده
This paper discussed the circuit level design and simulation of fractional-N frequency divider, a circuit block used mainly in frequency synthesizer. The design was done in schematic level. A low power 0.5 micron CMOS technology called CMOSIS5 used for modeling the circuit devices. The frequency divider was design for 900 MHz GSM standard mobile communication application. For the simulation, circuit level simulator SPICE was used. The circuit was run under 1 GHz input frequency. Simulation results show that the circuit was running well in this frequency input.

For extremely-scaled CMOS technologies, supply voltages well below 1V will be required to maintain reliability [1]. Analog and RF design with standard devices then becomes very challenging because of the significant reduction in both the available signal swing and the available overdrive for biasing. We present ultralow-voltage design techniques that maintain all node voltages between the suppl...
