Power Amplifier Design with 8 dBm Saturated Output Power in $D$-Band in 22-nm FDSOI Technology

International Conference on Modern Circuits and Systems Technologies, pp. 1–4

Abstract

$D$-band power amplifiers (PAs) are critical components for 6G communications. While unconditional stability in the frequency band of interest is regularly taken into account in the design process, the stability at lower frequencies are also required to be evaluated to avoid possible oscillation problems. In this paper, we propose a power amplifier in$D$-band stabilized from DC to$f_{max}$in simulation by introducing custom inductors at the gate terminals of the pseudodifferential stage with cross-coupled neutralization capacitance,$C_{N}$. The design methodology of the PA and the implementation of the inductors are comprehensively discussed. By cascading four stages with transformer matching networks, the PA achieves a gain of 16.2 dB, 8 dBm of saturated output power, and an$\text{OP}_{1 \text{dB}}$of 3.6 dBm.
