Abstract
A wideband power amplifier (PA), with 88% fractional bandwidth operating in the 700 MHz to 1.8 GHz range, which covers most of the standardized narrowband internet-of-things (NB-IoT) and LTE-M bands, is fully integrated in 22 nm CMOS FDSOI. A single-stage differential amplifier core, combined with an on-chip balun, realizes a single-ended output. A stacked circuit architecture, with 3.3 V LDMOS transistors as output devices and thin-oxide flipped-well transistors as the input common-source (CS) stage, enable a wide bandwidth and reliable operation at a supply voltage of 2.55 V. Capacitor banks with stacked thin-oxide transistor switches tune the PA frequency characteristics over the wide frequency range. The PA delivers a saturated output power (Psat) of up to +24.4 dBm with up to 45% power-added efficiency, which is compliant with the current 3GPP standard for NB-IoT and LTE-M. The maximum power-gain varies between 30.7 dB and 29.2 dB over the whole frequency range. The PA core circuit occupies 0.32 mm2 of silicon area, of which 0.2 mm2 is occupied by the low loss balun.
