Abstract
This article introduces a highly integrated
V-band frequency-modulated-continuous-wave (FMCW) radar
transceiver (TRX) in 40-nm bulk CMOS. It incorporates two
identical transmitter (TX) and receiver (RX) channels, enabling
not only traditional forward sensing but also full-360 ◦ detection.
The FMCW synthesizer is based on a cascaded-phase-locked-
loop (PLL) topology, enhancing chirp quality while reducing
the necessity for complex off-chip components. Additionally,
it generates extra clocks to en
