  • Transcurrent circuit and current-voltage transforming circuit using the transcurrent circuit
    Patent number: 5982206
    Abstract: A transcurrent circuit in which a first current flows in an output-stage circuit based on a second current flowing in an input-stage circuit and a given current transform ratio of the first current to the second current. In the transcurrent circuit, at least one of the input-stage circuit and the output-stage circuit in the transcurrent circuit is constructed with a plurality of transistors. Further, all the transistors in both of the input-stage circuit and the output-stage circuit have the same gate length.
