This paper presents the design of two lowvoltagedifferential class-E power amplifiers (PA) for DECTand Bluetooth fabricated in 130nm CMOS. In order tominimize the on-chip losses and to achieve a high efficiency atlow supply voltages, the PAs do not use on-chip outputmatching networks. At 1.5V supply voltage, the DECT PAdelivers +26.4dBm of output power with a drain efficiency(DE) and power-added efficiency (PAE) of 41% and 30%,respectively. The Bluetooth PA delivers +22.7dBm at 1V witha DE and PAE of 48% and 36%, respectively. A continuouslong-term test of 100 hours proves the reliability of thedesign.
