Abstract :
This paper presents a low power UWB radar transceiver IC, which is used to make a radar system with precise range accuracy. The range accuracy is allowed by a variable delay circuit which can control the delay by 5 ps resolution. The detecting range of the transceiver is from 0.15 m to 8.4 m. The measurement results show that the maximum error is 3.75 mm. The circuit is implemented in a 0.13 μm CMOS process with the die area of 1.28 × 1.07 mm2. The total power consumption of the core circuit is 6.89 mA with the supply voltage of 1.5 V.
