<p>PURPOSE: To reduce dependency against the inclination of the input signal waveform of an output change by providing a second differential cell having one input connected to output and the other input connected to a control circuit part provided with respective outputs connected to threshold input. CONSTITUTION: A transistor T9 is provided with a base B9 which is directly connected to an output terminal OUT as input for a second differential cell 9 and a collector C9 connected to a power electrode Vc. In the other transistor T10, the base B10 is connected to ground via a current power as second input and is connected to the emitter E11 of an npn-type transistor T14. T14 is connected to become diode constitution in the device 1, and the collector C14 is directly connected to the emitter E15 of the transistor T15. Threshold input S is connected to the collector C10 of the transistor T10 in the cell 9 and a comparator 1 is provided with the circuit part 10 effective for controlling a voltage value Vs appearing on threshold input S. Thus, dependency against the inclination of the input signal waveform of the output change can be reduced.</p> |
