Abstract: An electronic circuit includes first to third transistors. The first transistor has a first channel width and a first channel length and generates a first potential difference by passing an operating current based on a first operating voltage. The second transistor has a second channel width and a second channel length and generates a second potential difference based on the operating current. The third transistor generates a third potential difference based on a second operating voltage and the operating current. A sum of a level of the first operating voltage and a level of the first potential difference corresponds to a sum of a level of the second operating voltage, a level of the second potential difference, and a level of the third potential difference. The first channel width is greater than the second channel width, or the first channel length is longer than the second channel length.
