Abstract: A reference current/voltage generator includes a current mirror unit and a current-mode temperature compensation unit. The current mirror unit generates a first current, a first sum current and a second sum current flowing through first to third terminals thereof, and the first current, the first sum current and the second sum current are in a multiple relationship. The current-mode temperature compensation unit is electrically connected to the second and third terminals of the current mirror unit, and when a voltage on the second terminal is equal to a voltage on the third terminal, the first sum current is a sum of a current proportional to absolute temperature (PTAT) and a current complementary to absolute temperature (CTAT). The first terminal of the current mirror unit is an output terminal of the reference current/voltage generator and configured to output the first current as a reference current.
