Abstract :
A 1.3 GHz 0.5 /spl mu/m BiCMOS offset PLL realizes -132 dBc/Hz in-band phase noise while reducing re-radiated transmission by 53 dB. The circuit operates without an offset signal. Elements include digital phase detector with steering operating to 1.3 GHz and digital frequency divider with programmable modulus from 1 to 1.5 in steps of 0.03125. Current is 10 mA from 2.7 V. Die is 1.2 mm/sup 2/.
