Field programmable gate arrays (FPGAs) are¯exible programmable devices that are used in a wide variety of applications. The¯exibility of the FPGA hinders its performance due to the additional logic resources required for programmable hardware. The paper proposes a high speed SiGe heterojunction bipolar transistor (HBT) FPGA design co-integrated with CMOS in an IBM BiCMOS process. This device would be bitwise compatible with the Xilinx 6200, with operating frequencies in the 1±20 GHz range. To

Further power savings can be accomplished by integrating CMOS control into bipolar current trees and using a switchable current mirror to turn off unused current trees. The speed of bipolar combined with power savings of CMOS can now be merged to produce a new family of high speed FPGAs.
