摘要：PROBLEM TO BE SOLVED: To increase an operation speed of a differential amplifier including current mirror circuits which deliver outputs to the load side by currents. SOLUTION: The differential amplifier comprises means each of which is connected to a connection point between one of transistors to which two inputs are given respectively and a transistor to which a monitor current of one of current mirror circuits flows, and applies a minute current for preventing cutting off the transistor to which the monitor current flows, only when the input to the transistor to which the input is given is L.
