Abstract

See full text

To provide a mixer and a semiconductor device which each have a small circuit area and each of which operation capability is inhibited from being decreased due to heat. The mixer includes a differential portion, a current source, a first load, an input terminal, and a first output terminal; the differential portion includes a first and a second transistor; and each of the first and the second transistors includes a metal oxide in a channel formation region. A first terminal of each of the first and the second transistors is electrically connected to the input terminal and a current source and a second terminal of the first transistor is electrically connected to a first terminal of the first load and the first output terminal. The first load has a function of supplying a current between the first terminal and a second terminal of the first load by application of voltage to the second terminal of the first load, and the current source has a function of supplying a constant current to the current source from the first terminal of each of the first and the second transistors. The current source includes a transistor including silicon in a channel formation region, and the differential portion is positioned above the current source.
