A 77-GHz 8RX3TX Transceiver for 250-m Long-Range Automotive Radar in 40-nm CMOS Technology

An automotive 77-GHz long-range radar (LRR) with an 8-channel receiver (RX) and a 3-channel transmitter (TX) in 40-nm CMOS technology is presented. It integrates a 38.5-GHz phase-locked loop (PLL), a transmitter power detector (DET) and power calibration loop, a crystal oscillator (XO), built-in-self-test (BIST) circuits, an SRAM, an eFuse, a temperature compensation calibration loop with a lookup...
