Short-distance (<10cm) wireless communications applications are rapidly expanding. For instance, a fast file transfer by “touch-and-proceed data communication” provides a user-friendly interface for electronic products [1,2]. Wireless I/O’s may replace conventional connectors on a PCB to overcome performance limitations [3,4]. High-speed (>Gb/s), low energy dissipation (<100pJ/b), low bit-error-rate (BER<10-3), and low cost (small layout area in matured CMOS processes) are required as well as compliance with spectral regulation and EMI/EMS. None of the previous research achievements has satisfied all these requirements (Fig. 26.2.6). Non-coherent UWB transceivers are typically low speed and energy hungry; i.e. 15Mb/s with 2680pJ/b in a heterodyne transceiver [1] and 1Mb/s with 373pJ/b in a direct-conversion transceiver [3]. Millimeter-Wave radio is often used to raise the data rate at the cost of increase
