| Summary: | 碩士 === 國立交通大學 === 資訊科學與工程研究所 === 100 === Time-to-digital converter (TDC) is widely used in precise time measurement equipment and PLLs. How to produce a wide input range and high resolution TDC is an important design issues in this paper. The proposed TDC adopts the counter method to gain 193ns input measurement range and it uses time amplification method to improve Cyclic Vernier TDC resolution to be 2.6 ps. For fine resolution requirement, a 0.1ps dead zone phase detector is proposed to monitor the history of the phase difference between coarse and fine DCOs.
All circuits in the TDC are implemented by the TSMC 65nm 1P6M standard cell library and placed and routed by automatic EDA tools. The core area is 0.05 mm2 and the power consumption is 2.57 mW with 1 V supply voltage.
