A Novel Multi-Speed, Power Saving Architecture for SiGe HBT FPGA
نویسندگان
چکیده
The availability of SiGe HBT devices has opened a door for Gigahertz FPGAs. However, the large device power consumption limits its scale. In order to solve this problem, a Multiple-Speed Current Mode Logic design has been developed to provide variable power (and speed) settings. The performance of the Multiple-Speed Current Mode Logic architecture at the optimum setting exhibits similar performance to conventional Current Mode Logic designs. The Multi-Speed FPGA has been developed based on this new design. The economic power setting (lower speed setting) does not degrade its performance substantially. With this power saving technique the Multiple-Speed FPGA, therefore, can be scaled up in the future.

متن کاملA High Performance Field Programmable Gate Arrays Created by SiGe HBT BiCMOS
In 2000, the first high speed SiGe FPGA utilizing Current Mode Logic (CML) was proposed. The excellent high speed performance that CML allows made it a good candidate for use in high speed FPGA design. However, the large power consumption associated with CML (108mW for the FPGA building block) made the design difficult to scale up. To alleviate this problem, an improved FPGA with shorter propag...
متن کاملInP HBT Production Technology for 100 Gbps Lightwave Communications
InP HBT technology appears to offer the high speed, low power and basic producibility necessary to support a high-speed digital IC technology. Maximum clock speed of 53 GHz has been demonstrated at 40 mW per flip-flop (FF) as compared to well over 200 mW/FF for SiGe at slower speeds. At a power dissipation of less than 9 mW/FF, toggle rate is still a respectable 35 GHz. Producibility and high s...
