A 30.4-dB Dynamic Range Pulse-Modulated Class-E RF PA with 11-bit Digital Pulse Modulation Unit Achieving 25.3-dBm Psat and 32.3% Peak PAE

This paper presents a compact, high-efficiency pulse-modulated Class-E RF Power Amplifier (PA) with an 11-bit Digital Pulse Modulation (DPM) unit, achieving 25.3 dBm Psat and 32.3% peak Power Added Efficiency (PAE) in 22nm FD-SOI CMOS. Offering a 30.4 dB output power range, the DPM unit adds little area and efficiency overhead while reducing effectively AM-AM and AM-PM distortions. Operating from 1.4 to 1.85 GHz, the design enhances power backoff (PBO) efficiency with a 0.65 W/mm^2 power density.
