2.23~2.45GHz Fully Integrated PLL with Novel Prescaler and Loop Filter in 0.35m CMOS A 16mW

A 3mW inherently glitch-free phase-switching prescaler and a loop filter with a 0.2mW capacitance multiplier are proposed for a PLL synthesizer in 0.35m CMOS. The noise folding is minimized by optimal design of modulator and minimized PLL nonlinearities. The synthesizer has a 9.4% tuning range of 2.23-2.45GHz. The phase noise is -90dBc/Hz at 10kHz, and -128dBe/Hz at 10MHz offset.
