A 2.1-GHz monolithic frequency synthesizer with robust phase switching prescaler and loop capacitance scaling Conference Paper uri icon

abstract

  • This paper presents the design of a 2.1-GHz fully integrated fractional-N frequency synthesizer in 0.35um CMOS technology. The improved low-voltage, low-power, inherently glitch-free phase switching prescaler is used in this work. With capacitance scaling, large capacitors in the loop filter can be integrated on chip within small area. With several different digital modulators designed on chip, optimal design of the digital modulator for the fractional-N synthesizer will be investigated experimentally. The supply voltage is 1.5V for VCO and prescaler and 2-V for other blocks. The synthesizer dissipates 16mW and has an area of 0.85mm2 excluding pads.
