Abstract

This article presents a 76–81 GHz millimeter- wave (mm-wave) radar transceiver and a 2 × 8 multi-input multi-output (MIMO) antenna-in-package (AiP) for automotive radar applications. The proposed transceiver chip consists of a frequency-modulated-continuous-wave (FMCW) radar waveform generator, a 3-channel sub-transmitter (Tx), and a 4-channel receiver (Rx) with integrated analog-to-digital converters (ADC). A two-point modulation scheme and a digital- to-analog converter’s (DAC) dynamic bias te
