The properties of some passive and active devices such as inductors, capacitors, transmission lines, translbrmers and transistors in mm-wave frequency band are discussed. Self-healing technique dealing with PVT variation, res- onant mode switching technique to enhance frequency tuning range of voltage controlled oscillator （VCO） and dual mode technique for power amplifier （PA） efficiency enhancement are introduced. At last, A fully-integrated 60 GHz 5 Gb/s QPSK transceiver with the transmit/receive （T/R） switch in 65nm CMOS process is introduced. The measured error vector magnitude （EVM） of the TX is -21.9 dB while the bit error rate （BER） of the RX with a -52 dBm sine-wave input is below 8e-7 when transmitting/receiving 5 Gb/s data. The transceiver is powered by 1.0 V and 1.2 V supply （except the phase-frequency detector and charge-pump in the frequency synthesizer which are powered by 2.5 V supply） and con- sumes 135 mW in TX mode and 176 mW in RX mode.展开更多
