A single-chip CMOS PHS cellphone, integrated in a 0.18-mum CMOS technology, implements all handset functions including radio, voice, audio, MODEM, TDMA controller, CPU, and digital interfaces. Both the receiver and transmitter are based on a direct conversion architecture. The RF transceiver achieves -106 dBm receive sensitivity and +4 dBm EVM-compliant transmit power. The local oscillator, based...
A single-chip IEEE 802.11g-compliant WLAN radio that implements all RF, analog, and digital PHY and MAC functions is implemented in a 0.18 /spl mu/m CMOS technology. The IC transmits 4 dBm EVM-compliant output power for a 64QAM OFDM signal. The overall receiver sensitivities are -95 dBm and -73 dBm for data rates 6 Mbit/s and 54 Mbit/s, respectively.
