  • Patent number: 5600267
    Abstract: A CMOS circuit is disclosed for translating a signal from CML to CMOS logic voltage levels. The CMOS circuit includes two amplifier circuits coupled in parallel. The first amplifier circuit comprises of a programmable circuit and a CMOS inverter such that the CMOS inverter can be programmed "on" or "off" by the programmable circuit. The programmable circuit includes a programmable element which may be implemented using a fuse or floating gate technology. The second amplifying circuit comprises of a CMOS inverter. When the CMOS inverter in the first amplifier circuit is powered "on", the CMOS circuit is operating in a full power mode at high speed with both CMOS inverters operating. When the CMOS inverter in the first amplifier circuit is powered "off", the CMOS circuit is operating in a low power mode at a slower speed with only one CMOS inverter operating.
