in modern-day handheld computing devices around the unlicensed 57-to-71GHz band, the IEEE 802.11ay standard [1] supports 2-to-4× bonding of 2.16GHz channels (i.e. 4.32 to 8.64GHz), constellations up to 64QAM, and spatial MIMO. To support such wideband TX, prior linear 60GHz solutions [2] employ baseband modulation followed by a linear upconversion and PA with saturated power of ~10dBm. For OFDM and high-order single-carrier (SC) modulations, the PA operates in significant power back-off, leading to poor average output-to-DC (Pout-to-Pdc) power efficiency (<1.5%). Additionally, for spectral compliance, these solutions use off-chip pulse-shaping with 8-to-12b, 25-to-65GS/s arbitrary waveform generators (AWG). Implementing such high-performance DACs on-chip would
