Electronic circuit and semiconductor device

摘要

An electronic circuit includes: first circuits each including a first FET having a source supplied with at least one of a first voltage and a second voltage; and a second circuits each of which is associated with a respective one of the first circuits, and generates a back bias voltage applied to the first FET so as to change in accordance with a change of at least one of the first and second voltages.
