dc.description.abstractWe present a 1.9-GHz Personal Handy-phone System (PHS) transceiver, fully integrated and fabricated in 0.25-mum CMOS technology. The receiver is based on a 150-kHz low-IF architecture and meets the fast channel switching and DC-offset cancellation requirements of PHS. It includes a low-noise amplifier (LNA), a downconversion mixer, a complex filter, and a programmable gain amplifier. A fractional-N frequency synthesizer achieves seamless handover with a 25 mus channel switching time and a phase noise of -121 dBc/Hz at a 600-kHz offset frequency, with compliant ACS performance. The receiver provides -105 dBm sensitivity and 55 dBc ACS at a 600-kHz frequency offset. The transmitter is based on the direct modulation architecture and consists of an upconversion mixer and a pre-driver stage. The gain of the pre-driver is digitally controllable to suit any type of commercial power amplifier. The transmitter shows a 3% EVM and a 65 dBc ACPR at a 600-kHz offset frequency. The whole transceiver occupies 15.2 mm2 and dissipates 70 mA in RX and 44 mA in TX, with a 2.8-V supply.en
