Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/229385
Kind Code:
A1
Abstract:
Provided is a novel semiconductor device. This semiconductor device has a mixer circuit and a bias circuit. The mixer circuit has a voltage current conversion unit, a current switch unit, and a current voltage conversion unit. In addition, the bias circuit has a bias supply unit and a first transistor. The voltage current conversion unit has a second transistor and a third transistor. The bias supply unit has a function of outputting a bias voltage to be supplied to a gate of the second transistor and a gate of the third transistor. One of a source or a drain of the first transistor is electrically connected to the gate of the second transistor and the gate of the third transistor. When a bias voltage is supplied, the first transistor is set to an off state. When supply of a bias voltage is stopped, the first transistor is set to an on state.
