Abstract
An impedance conversion circuit for the use with a video apparatus, an audio apparatus, or a communication apparatus is provided. The impedance conversion circuit can be used at a frequency higher than that conventionally used and is suitable for formation as an integrated circuit. A video apparatus using this impedance conversion circuit, and the like are also proposed. Driving current is supplied to first and second terminals of an impedance circuit in accordance with voltages of first and second input terminals, respectively, and current is made to flow out of the second and first output terminals in accordance with the first and second terminal voltages of the impedance circuit, respectively.
