Abstract: A power supply circuit includes a charge pump circuit configured to generate an output voltage by boosting an input voltage received at an input terminal and to provide the output voltage at an output terminal. A current supply circuit of the power supply circuit includes a first current source that supplies a first current that increases with time. The current supply circuit supplies current to the input terminal of the charge pump circuit. An insulated gate field effect transistor has a control electrode connected to the output terminal of the charge pump circuit. The insulated gate field effect transistor has a first electrode receiving a first voltage and a second electrode outputting a second voltage to, for example, a load circuit. The level of the second voltage can be determined according to the levels of the output voltage of the charge pump circuit and the first voltage.

Abstract: According to one embodiment, a differential amplifier includes a differential circuit, an output circuit, and a clipper circuit. The differential circuit generates a pair of differential currents in accordance with a difference in potential between a pair of input signals. The output circuit receives the pair of differential currents and generates an output voltage in accordance with the current difference. The clipper circuit suppresses the output voltage within a range to be able to convert to a low level or to a high level being higher than the low level.
