Abstract
PURPOSE:To stabilize the output by increasing/decreasing one input as soon as an output transistor(TR) is turned off from ON or vice versa. CONSTITUTION:The input/output of a 1st current mirror circuit 6 is connected to the output of a differential amplifier 3, the base of a 1st TR 1 is connected to one output of the differential amplifier 3, the power supply of a 2nd current mirror circuit 13 is connected to the collector of the 1st TR 1 and one input of the differential amplifier 3 and the resistor 14 are connected to the input of the 2nd current mirror circuit 13 to keep the other terminal of the resistor 14 to a fixed potential and the output of the 2nd current mirror 13 to make the output of the 2nd current mirror 13 as the circuit output I0. When an inverted level has a width while the 1st TR 1 is turned from ON to OFF or vice versa and even if the input comparison level has a minute change, the 1st TR 1 keeps the preceding state. Thus, the stable output is attained.
