A successive approximation method is presented to calibrate the loop bandwidth by digitally adjusting the switch size of the master-slave sampling filter. This brief is fabricated in 45 nm CMOS technology. Its active area is 0.013 mm2. The power consumption is 3.6 mW at 2.4 GHz for a supply of 0.9 V. The integrated jitter over 1 kHz to 100 MHz is 3.6 ps. With the supply voltage of 0.88V0.92V, the variation of the loop bandwidth is reduced from 18.7% to 4.6% by using the loop bandwidth calibration. ? 2004-2012 IEEE. |
