This paper presents a 65nm CMOS-power amplifier (PA) designed for WiFi communications. The PA is based on a Half Stacked Folded Differential Structure (HSFDS) cascoded. The PA is designed for the WiFi 802.11n standard. The power amplifier provides 24.5 dBm output powers with 25% of power added efficiency (PAE) at 2.45 GHz. The linear gain is 15.5 dB and the compression point (OCP1) is 18.5 dBm. In order to meet the 802.11n requirements, the PA is linear until 16 dBm, which is the maximum output power required by this standard.
