Abstract
In this paper, a novel architecture of programmable divider with fifty percent duty cycle output and programmable dividing number has been proposed. Through HSPICE simulation, a 900MHz frequency synthesizer with proposed frequency divider has designed in a standard 0.25$\mu\textrm{m}$ CMOS technology. To verify the operation of proposed frequency divider, a chip had been fabricated using 0.65$\mu\textrm{m}$ 2-poly, 3-metal standard CMOS processing and experimental result shows that the proposed frequency divider works well. The designed voltage controlled oscillator(VCO) has a center frequency of 900MHz, a tuning range of ${\pm}$10%, and a gain of 154MHz/V. The simulated frequency synthesizer performance has a settling time of 1.5${\mu}\textrm{s}$, a frequency range from 820MHz to 1GHz and power consumption of 70mW at 2.5V power supply voltage.
