Abstract

This paper presents a sub-1GHz RF front-end including a LNA, a PA and an off-chip balun. There is no inductor in either the LNA or the PA, so the layout area of this circuit is small, which is about 0.275mm2 designed in 110nm CMOS technology. For the RX mode, the voltage gain is 26.5dB while the noise figure is about 2.23dB. The S11 parameter is less than-10dBm and the IIP3 is-4.825dBm. For the TX mode, a class-E PA is used to obtain higher efficiency. It can deliver 17.4dBm output power with a power added efficiency (PAE) of 53%. It consumes 4.2mA for the RX mode and 50mA for the TX mode from a 1.5V power supply.
