摘要
This paper presents a K-band FMCW radar transceiver IC, which is integrated in 0.13-mu m CMOS technology. In the transmitter part, the class-C topology is adopted in the VCO block to achieve good phase noise performance. In the receiver part, the high gain of the LNA sufficiently suppresses the noise of the next stages to achieve a good noise figure in the receiver and the linearity of the receiver was improved by adoption of a gain control block, thereby achieving a wide dynamic range. As a result, a conversion gain of 35.7 dB, a P1dB of -12.7 dBm, and a DSB noise figure of 5.5 dB are achieved in the receiver part. The tuning range of 23.8 similar to 24.5 GHz and the phase noise of -103.1 dBc/Hz @ 1MHz offset are achieved in the transmitter part. The transceiver chip consumes 181.5 mW from a 1.5 V power supply. Using this chip, the K-band FMCW radar module is implemented and verified by measurement of the distance of an object.
