  • ECL-CMOS level conversion circuit
    Patent number: 5585743
    Abstract: In a level conversion circuit for converting a pair of first-level signals into a pair of second-level signals, an input buffer circuit converts the pair of first-level signals into a pair of buffered signals which vary within a first voltage range situated below a second voltage range within which the pair of first-level signals vary. An amplifier circuit, which includes a plurality of CMOS differential amplifier circuits cascaded, converts the pair of buffered signals into the pair of second-level signals varying within a third voltage range broader than the second voltage range of the pair of first-level signals.
