  • BiCMOS digital amplifier
    Patent number: 5304869
    Abstract: A BiCMOS circuit for amplifying the difference voltage between two input voltage signals. The BiCMOS circuit of the present invention includes two bipolar junction transistor which receive the two input voltage signals and each drive a cascode-connected PMOS device. The drains of the cascode-connected PMOS devices are coupled to the input and output of a current mirror, wherein the output of the current mirror is the output of the BiCMOS circuit.
