に供給されるようにした電流源回路。[Claims for Utility Model Registration] In a current source circuit connected to a circuit network, an active element is provided, the source of this active element is connected to a reference potential, and the gate is connected to one end of a capacitive component, A switch is provided between the drain and gate of the element, and the drain is connected to a movable contact of a changeover switch, a first fixed contact of the changeover switch is connected to the circuit network, and a second fixed contact is connected to a predetermined potential. The other end of the capacitive component is brought to the first potential during an arbitrary period, and the changeover switch is switched to the second fixed contact side during a predetermined period included in this arbitrary period, and the switch is turned on. By applying the predetermined potential to the drain gate of the active element, the capacitive component is charged with a voltage equal to the difference between the first potential at this time and the gate potential of the active element, and for a desired period of time. The other end of the capacitance component is set to the second potential, and the changeover switch is switched to the first fixed contact side and the switch is turned off, whereby a current based on the voltage charged in the capacitance component is generated. A current source circuit configured to cause current to flow through the active element and supply the current to the circuit network.
