A 19.2mW 1Gb/s secure proximity transceiver with ISI pre-correction and hysteresis energy detection

This paper presents a 1Gb/s 6.5-to-8.5GHz transceiver for secure proximity communication systems. A prototype transceiver implemented in 65nm CMOS achieves the maximum data rate of 1Gb/s with the sensitivity of -53dBm and the communication range of 15cm. Consuming only 19.2mW, the proposed ultra-wideband (UWB) transceiver enables future applications such as smartphone-mirrored high-resolution display systems which require low power mainly for the transmitter in the smartphone, thus making it possible to further improve the transceiver performance with the complex receiver in the display equipment.
