Abstract
This paper presents a fully integrated class-F power amplifier (PA) with two stages, which is fabricated using Global Foundry (GF) 0.13 \(\upmu\)m CMOS process and is packaged in a 6-pins. The proposed circuit includes a power stage and a driver stage, and is designed to operate in class-F conditions. To avoid excessive power consumption, a current-reused topology is used in the driver stage. In addition, in order to reduce the complexity of the circuit design, the circuit is fabricated using lumped components. The experimental results show that the implemented PA delivers a power added efficiency (PAE) of 43.9% at an output power of 13.5 dBm at a 3.5 GHz operating frequency point. For verification, when driven by a 5 MHz LTE signal, the proposed PA obtains an adjacent channel leakage ratio (ACLRs) of − 20 dBc/− 20.5 dBc. After digital pre-distortion (DPD) ACLRs can achieve \(-\) 41.5 dBc/\(-\) 42.5 dBc at ± 5 MHz. Furthermore, the chip area including testing pads is \(1.31\times 1.12\) mm\(^{2}\).
