Abstract :
A 5.4 GHz All-Digital Phase-Locked Loop (ADPLL) is presented in this paper. The ADPLL is designed in 65nm CMOS process. A 7 bit wide output swing and high linearity digital-to-analog converter (DAC) is used in this ADPLL to achieve good jitter performance. The proposed current-mode DAC with dual compensation circuits compensates the channel modulation effect. It demonstrates output swing of 1 V and DNL of 0.1 LSB. The frequency resolution of the DCO is 52 kHz. The rms jitter of the ADPLL is 0.53 ps.
