Third-order fractional interpolator

WebThe phase interpolator has a resolution of 6 bits and is implemented in a 16-nm CMOS process. The maximum differential non-linearity is measured to be 0.1 LSBs at a 192 ps input time delta. The circuit draws 0.2 mW from a 0.8 V supply, and occupies 0.004 mm2. Index Terms—Phase interpolator, PLL, low noise, high linearity I.
