- Abstract
- This thesis presents a synthesized 2 GHz fractional-N ADPLL with a dual-referenced interpolating TDC. The proposed TDC measures fractional phase by referencing adjacent two integer phases and achieves gain matching without any calibration scheme. It also improves linearity with little sensitivity to process, voltage and temperature variations by averaging nonlinearity errors of opposite polarities. Except for DCO, the PLL is designed only by RTL-level behavioral descriptions and synthesized with a standard cell library. The PLL is implemented in 65 nm CMOS with an active area of 0.047 mm2 and achieves a stable in-band phase noise of lower than -100 dBc/Hz in a wide range of supply voltage from 1 to 1.4 V.
