<p>PURPOSE:To obtain the stable pulse output by inserting the diode between the non- inverse input terminal and the differentiating circuit and at the same time connecting the resistance and the diode connected in series to the resistance deciding the output pulse time and in parallel. CONSTITUTION:With application of the pulse to input terminal 2, the differential pulse is applied to operation amplifier 1. And operation amplifier output (c) of output terminal 3 is held at saturation voltage VOL and voltage V of the inverse input terminal approximates to VOL by the value which is decided with time constants R2 and C2. Then when voltage V becomes higher than non-inverse input terminal voltage V+ owing to the discharge of capacitor 5, charge time constant Tr of capacitor 5 features Tr T to discharge time constant T. And thus voltage V reaches clamping voltage VF immediately.</p> |
