Multiband multi-standard transmitter using a compact power amplifier driver

• This paper presents a multistandard transmitter solution using a new power amplifier (PA) driver [1] operating in the broadcast, mobile, and the 2&5 GHz ISM bands. The use of dual-loop feedback in the driver provides a matched output without area consuming matching networks. The circuit size is as small as 0.3 mm(2) for the used 0.18 mu m CMOS process, saving about 0.7 mm(2) silicon area. Measurement results show a gain higher than 7.8 dB with a maximum output power of +4 dBm for all bands and using a supply voltage of 1.8V.
