A 5.4GHz wide tuning range CMOS PLL using an auto-calibration multiple-pass ring oscillator
Författare
Summary, in English
A 5.4GHz multiple-pass ring voltage controlled oscillator (VCO) based phase-locked loop (PLL) is described. For the sake of active devices’ sensitivity to process and temperature regarding ring oscillators, an effective automatic frequency calibration scheme is proposed. A new process-independent differential to single (DTOS) is
used to adjust control voltage range and loop gain. The chip is implemented in 0.18-um CMOS process
and achieves phase noise of -100dBc/Hz@1MHz
and a 40% tuning range.
