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.
