Circuit device, electronic apparatus, and moving object

摘要

In order to achieve a circuit device capable of stably supplying an antenna with electric power in a broad power range to output a transmission signal, the circuit device includes a current source adapted to supply a first current in a first operation mode, and supply a second current higher than the first current in a second operation mode, and a drive section supplied with the electric power from the current source, and adapted to perform drive for outputting a transmission signal to an antenna via a matching circuit.
