摘要
This paper proposes a 56 - 65 GHz highly-integrated frequency modulated continuous wave (FMCW) radar transceiver in 65 nm CMOS, featuring 7.8 dB NF and an 8 GHz chirp-bandwidth. The chip integrates 4-channel receiver (Rx) and 3-channel transmitter (Tx). A 15 GHz PLL and frequency multipliers with reconfigurable capacitor arrays are employed to generate the wideband signal with an 8 GHz chirp bandwidth. The Tx achieves a 14.08 dBm maximum output power, while the Rx exhibits a 7.8 dB NF at 5 MHz IF and a 66 dB conversion gain (CG). The measured phase noise is -97.5 dBc/Hz at 1 MHz offset in 60 GHz. And the measured best phase noise performance is -100.3 dBc/Hz at 1MHz offset for a 52.4 GHz carrier. The proposed transceiver occupies 4.8 mm x 2.8 mm area including pads, and burns 610 mW power consumption.
