Abstract
The invention relates to the interfacing of high speed, low voltage data streams with CMOS circuits and, more specifically, to converting low voltage, differential ECL signals levels to higher voltage levels which are compatible with CMOS circuits while maintaining high speed and sufficient drive capability. This is accomplished by making first stage inverters,and,as geometrically small as possible subject to the design rules in use to minimize the capacitance at the input of these inverters. The inputs of the first stage inverters are clamped by bias circuits,and,at DC levels so as to provide a narrow range of operation. Additional output inverters,and,act as buffers to provide the needed capacitive load drive capability.
