A 25 Gb/s 60 GHz digital power amplifier in 28nm CMOS


This paper presents a 60 GHz class-E digital power amplifier (DPA) that generates energy-efficient, non-constant envelope modulations up to 25 Gb/s. The DPA achieves a peak drain efficiency of 17.7% at a V<inf>sat</inf> of 7.4 dBm. By means of direct digital amplitude modulation of the 6-bit output stage, the DPA produces error-free, high-order… (More)
