A biasing circuit includes an increasing circuit, a supplying circuit, a bias outputting circuit and a bias outputting circuit. The increasing circuit outputs a drive voltage, and the supplying circuit is connected in parallel to the increasing circuit and outputs a drive voltage. The bias outputting circuit outputs a bias output to a biased circuit in response to the drive voltage from the increasing circuit or the drive voltage from the supplying circuit. The control circuit controls the increasing circuit and the supplying circuit based on the bias output from the bias outputting circuit.
