This paper presents a 286-GHz wideband amplifier implemented in a 28-nm CMOS process. To overcome the inherent maximum oscillation frequency (fmax) limitation of the process, a custom-designed NMOS la...
This paper proposes a D-band bidirectional amplifier using a lossy U-boosting network with off-state transistors, embedded inductors, and a Wheatstone-bridge-like feedback network to enhance Mason’s i...
A 76–81 GHz FMCW automotive radar transceiver is presented, implemented in 22 nm CMOS-FDX. Its key features are four TX channels with 7-bit phase rotator delivering controllable output power up to +15...
This work presents a built-in self-test (BIST) system designed for a 60GHz MIMO FMCW radar SoC. Compared to conventional mmWave RFIC/module level tests which require expensive test equipment and exten...
This paper presents a 77-GHz FMCW automotive radar transceiver implemented in 28-nm FD-SOI technology. The transceiver integrates a single-channel transmitter, a single-channel receiver, and a frequen...
A reconfigurable UWB receiver supporting the IEEE 802.15.4ab narrowband-assisted multi-millisecond (NBA-MMS) ranging scheme is presented. To minimize the area overhead of NB support, a current-amplifi...
Encouraged by the proliferation of the 802.15.4a/z IR-UWB standard, the next generation, the 802.15.4ab, aims to extend the ranging distance by including a provision for narrowband radio assistance. S...
This paper presents a frequency tripler employing a phase-alignment-based harmonic recombination technique. By applying replicas of the input signal shifted by specific phase offsets, the unwanted har...
This paper presents the design and measurement of a SiGe D-band frequency quadrupler, which is composed of two push-push frequency doublers (FDs) and an inter-stage driver amplifier. The simulation re...
This paper presents a broadband ×6 amplifier-multiplier chain (AMC) implemented in a 130-nm SiGe BiCMOS process, comprising a differential tripler-driver amplifier, a push-push doubler, and a 95–185GH...
