CMOS UWB transmitter and receiver with silicon integrated antennas for inter-chip wireless interconnection

Ultra-wideband (UWB) transmitter and receiver circuits were developed and inter-chip wireless communication with silicon integrated antennas using Gaussian monocycle pulse (GMP) was performed. Inter-chip data transmissions for stacked Si LS's having GMP transmitter circuits by use of 0.18 mum CMOS technology were performed. Differential Gaussian monocycle pulses with data rates of 200 Mbps were generated. On-off-keying (OOK) modulation scheme was adopted for data transmission. Synchronous GMP receiver having double GMP generators was developed. Clock timing and OOK data pulses were alternately sent using on-chip transmitting antenna. 200 Mbps data recovery was achieved at the distance of 0.5 mm.
