A full‐duplex transceiver for 20‐Gbps high‐speed simultaneous bidirectional signaling across global on‐chip interconnections

This paper presents a high-speed simultaneous bidirectional transceiver (SBT) for on-chip wireline communications. A MOS hybrid transistor is utilized to split the received data from superimposed signal at both ends of interconnection with assistance two drivers, namely main and auxiliary. Moreover, high-pass filter (HPF) used as differentiator generate echo cancelation signal. Consequently, echo-cancelation signaling (SBS) realized by combination device differentiator. The proposed SBT has been designed evaluated using 28-nm CMOS technology over narrow 5-mm interconnection, which possesses 11.9-dB loss Nyquist frequency (half bit rate). energy-efficiency full-duplex (FDT) 20-Gbps transmission 0.147 PJ/b/mm. performance results show that better overall compared previous architectures reported in literature date. layout presented occupies low area 1574 μm2.
