Title: Digital signal drive circuit
Inventor: KATO NORIAKI
IPC: H03K19/0175
Filed: 1991-05-27
Abstract: PURPOSE:To adjust the circuit so that a leading/trailing waveform is always made constant against fluctuation in a capacitive load. CONSTITUTION:When a leading of an output voltage of a MOS transistor(TR) 13 is slower than a leading of reference leasing waveform, an input voltage to a noninverting input terminal is higher than an input voltage to an inverting input terminal of a differential amplifier 12 and the MOS TR 13 is turned on. As a result, a resistance of an output resistor Ro of the MOS TR 13 is much more lowered thereby adjusting the leading waveform to be closer to the reference leading waveform. Moreover, when a load 16 is small and the leading waveform of the MOS TR 13 is faster than the reference leading waveform, the input voltage to the inverting input terminal is higher than the input voltage to the noninverting input terminal of the differential amplifier 12 and the MOS TR 13 is turned off. Thus, the resistance of the output resistor Ro of the MOS TR 13 is much more increased thereby adjusting the leading waveform to be closer to the reference leading waveform.
