Abstract
A current mirror circuitis formed to have a current ratio (a transistor size ratio) of 1:m. As well, respective pairs of nMOS transistors MN, MNand nMOS transistors MN, MNare formed to have a current ratio of:m. Two currents output from the current mirror circuitare each distributed to two. The distributed currents flowing in the nMOS transistors MN, MNare added and are then allowed to flow into one resistor R. Hence, for the resistor R, only one resistor in which current of double flows suffices when m=1, for example. This effortlessly reduces the necessary resistance to one fourth.
