Abstract :
A current-controlled oscillator (CCO) with 32ps phase resolution is realized by coupling ring oscillators in a 65nm CMOS process. A compact layout method achieves 36times46mum2 area and multiphase outputs whose timing errors are small. A CCO with 63 output phases is used in the PLL for a DVDtimes16 write system. The measured DNL of the output phases is within 1.0LSB at 490MHz
