Reconfigurable FPGA's in the 1-20 GHz Band with HBT BiCMOS
-- This paper describes the operation of a field programmable gate array (FPGA), the basics of current mode logic, and examines the idea of creating a SiGe heterojunction bipolar (HBT) version of the Xilinx 6200 FPGA. A new proposed device would be bitwise compatible with the 6200, but would operate in the 1-20 GHz range due to the HBT technology being used for the logic and routing and CMOS for storing the configuration bits. This is possible due to the IBM cointegration process of a HBT with a BiCMOS process. Information in this paper is based on an HBT having a fT of 50 GHz, but later in 1999 IBM will be unveiling a process that will double the speed. By replacing and redesigning key parts of the 6200 FPGA, a 100-200X operating speedup is possible. The core logic cell in the 6200 consists of two input multiplexers and flip-flops, which can easily be converted to current mode logic (CML). Routing in a conventional FPGA is done via pass transistors, which can act like a low pass filte...
