An integrated X-band FMCW radar transceiver in 130-nm CMOS technology

A fully integrated low power X-band radar transceiver in 130 nm CMOS process is presented. The highly integrated sub-system includes a low-noise amplifier (LNA), a voltage buffer, a down-conversion mixer, a low pass filter (LPF), a voltage controlled oscillator (VCO), a VCO buffer and two power amplifier (PA) drivers. The receiver provides a voltage conversion gain of 10 dB. The output power of the transmitter including the PA is -2 dBm. The total DC power consumption of the transceiver is 36 mW from a 1.2 V supply and the size of the chip is 670 × 716 μm2.
