Mo1B-2 : A 77GHz 8RX3TX Transceiver for 250m Long Range Automotive Radar in 40nm CMOS Technology
This paper presents a fully integrated 77 GHz transceiver for long range automotive radar with a 2 × 8 time-division-multiplexing multi-input multi-output (TDM-MIMO) technique in 40 nm CMOS technology. The MMIC integrates an 8-channel receiver (RX), a 3-channel transmitter (TX), a phase locked loop (PLL), a TX power detector and a power calibration loop, an SRAM, an eFuse, a temperature compensation calibration loop with look up table (LUT) and a temperature sensor, a serial peripheral interface (SPI), and a MIMO control logic. The RX shows noise figure (NF) of 8.7 dB and input-referred 1 dB compression point (IP1dB) of -7.4 dBm. The RX with the worst condition shows NF of 14 dB and IP1dB of -10 dBm. The TX shows output power of 14.1 dBm and phase noise of -116 dBc/Hz at 12.5 MHz offset frequency. The radar module demonstrates the detection range of 250 m.

Tatsunori Usugi, Denso Corporation, Japan, presents the co-authored paper: Mo1B-2: A 77 GHz 8RX3TX transceiver for 250 m long range automotive radar in 40 nm CMOS technology.
