57-65 GHz differential and transformer-coupled power and variable-gain amplifiers using a commercial 90 nm digital CMOS process are presented. On-chip transformers combine bias, stability and input/interstage matching networks to enable compact designs. Balanced transmission lines with artificial dielectric strips provide substrate shielding and increase the effective dielectric constant up to 54...
As chip multiprocessors scale to a greater number of processing cores, on-chip interconnection networks will experience dramatic increases in both bandwidth demand and power dissipation. Fortunately, promising gains can be realized via integration of radio frequency interconnect (RF-I) through on-chip transmission lines with traditional interconnects implemented with RC wires. While prior work has...
In this paper, we propose a novel on-chip global interconnect that would meet stringent challenges of core-to-core communications in data rate (up to 100 Gbps /link), latency and re-configurability for future chip-microprocessors (CMP) with efficient area and energy overheads. We discuss the limitations of traditional RC-limited interconnects and possible benefits of multi-band RF-interconnect (RF-I)...
