title = "An Ultra-Compact and Wideband D-band Power Amplifier in 28nm CMOS with Area-Efficient Coupled Line-Based Matching Network",
abstract = "This paper presents an ultra-compact and wideband D-band power amplifier (PA) utilizing area-efficient coupled line (CPL)-based matching networks. The design overcomes the size limitation in the signal propagation direction by employing CPL-based matching networks and shunt capacitors, enhancing bandwidth while achieving a compact form factor. Implemented in a CMOS 28 nm process, the proposed 3-stage PA achieves a 3-dB bandwidth of 45.1 GHz with a peak gain of 12.2 dB, an OP 1 dB of 7.6 dBm, and a power-added efficiency (PAEmax) of 10.2\%. With a core area of only 0.24 {\texttimes} 0.065 mm2, the PA achieves the highest OP1dB per unit area among D-band PAs based on CMOS bulk process, making it a leading candidate for 2-D scalable D-band beamforming transmitter arrays.",
