Time-to-Digital Converter (TDC) provides picosecond accuracy timing and is widely used in many applications such as Light Detection and Ranging (LIDAR), 3-D vision, and ultrasonic flow sensors. This paper introduces a 2-channel TDC with two-level resolution control architecture. Designed in a 180 nm CMOS process, the TDC occupies an area of 2.3 mm $\times 1.3$ mm and achieves 20 ps resolution at 2 Msps measurement rate.
