Abstract
The object of this invention is to realize high-speed rise and/or fall characteristics for amplifier without increasing transistor size or current consumption. A first rise sensing circuit and a second a sensing circuit are connected to main circuit . The first sensing circuit has a PMOS transistor which functions as a rise sensing transistor, a pair of NMOS transistors and , which form a current-mirror circuit, and a PMOS transistor , which drives the PMOS transistor used for speed up in main circuit . The second sensing circuit has a PMOS transistor , which functions as a fall sensing transistor, a pair of NMOS transistors and , which form a current-mirror circuit, and a PMOS transistor used for driving the PMOS transistor used for speed up in main circuit
