Abstract
This paper presents an eight-unit class-D power amplifier (PA), implemented in 28-nm CMOS. The PA is designed to utilize tri-phasing modulation, which combines coarse-amplitude polar modulation with fine-resolution outphasing components. This new technique enables achieving the back-off efficiency of multilevel outphasing without linearity-degrading discontinuities in the output waveform. Each PA unit contains a cascoded output stage with a 3.6-V supply voltage, and on/off logic enabling multilevel operation controlled by low-voltage signals. The PA achieves a peak output power of 29.7 dBm with a 34.7% efficiency, and is verified to operate with aggregated LTE signals at bandwidths up to 60 MHz at 1.7-GHz carrier frequency.
