1. A current generation circuit, comprising:
a mirroring circuit suitable for charging a voltage, wherein a level of a charged voltage by the mirroring circuit varies in response to changes in a level of a power voltage; a comparison circuit suitable for comparing the charged voltage with a feedback voltage, wherein the comparison circuit includes an operational amplifier having a first input terminal to which the charged voltage is applied and a second input terminal to which the feedback voltage is applied; and a current driving circuit suitable for generating a current based on a voltage output from the comparison circuit, wherein the mirroring circuit, the comparison circuit and the current driving circuit receive the power voltage being supplied from the same voltage source, and the charged voltage, the feedback voltage and the voltage output from the comparison circuit are varied at the same time. |
