TransferJet™ is an emerging high-speed close-proximity wireless communication standard, which enables a data transfer of up to 522Mbps within a few centimeters range. We have developed a fully integrated TransferJet SoC with a 4.48-GHz operating frequency and a 560-MHz bandwidth (BW) using 65nm CMOS technology. Baseband filtering techniques for both a transmitter (TX) and a receiver (RX) are proposed to obtain a sensitivity of -70dBm with low power consumption. The SoC achieves an energy per bit of 0.19nJ/bit and 0.43nJ/bit for the TX and the RX, respectively, We have also built the world's smallest module prototype using the SoC, which is suitable for small mobile devices.
