What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
Why is input resistance low and output resistance high in transistor?
The input resistance of a trasister is jst like pn junction of a diode which has a breakdown voltage of .7v for silicon and the output resistance is like a reverse bias of a diode and hence the resistance is high
What will happen when a dc source is used in front of a diode in half wave rectifier?
If the DC source biases the diode off, then the output will be zero. If it biases the diode on, then the output will be DC, with the voltage being nearly the same as the input voltage.
What is the output of a diode can be?
A diode itself has no input or output.The circuit containing the diode usually has an input and an output, maybe even more than one of each. The output of this circuit will depend on far more than the diode as well as depending on the type of diode used.Theoretically: if a diode is connected across the secondary output of a stimulated transformer, you would read a half wave at the frequency of the source across diode.Such a circuit would cause any real diode to explode due to lack of any current limiting and the resulting high power dissipation in the diode.Hence "Theoretical". That's kind of what "Theoretical" means.
Why diode logic gate is not suitable for cascading operation?
the pullup or pull down resistance in the diode logic gate makes it a high output resistance device.If u try to drive another diode logic gate with it the output voltage of the first gate will be affected by the resistance in the second gate.A diode logic gate should always drive a high input resistance input.
How does the cut in voltage effects the output of a diode clipper?
For answering this question we have to consider the constant voltage drop model of the diode which says that if voltage across diode is less then its cut in voltage than assume diode to be open circuit and if it is greater then assume diode to be short circuit.Till the input voltage is less than the cut in voltage, diode is open circuit(thus no current through the circuit). Thus entire input voltage appears across the diode as output.When input voltage is greater than or equal to cut in voltage, then short circuit the diode. Thus, there will be no voltage drop across the diode as output.Thus cut in voltage decides when to consider the diode open circuit and when short circuit. It decides when the diode will have output when it will not.
Disadvantage of using diode as shunt element in clipper circuit?
In shunt clippers, when the diode is in off condition, transmission of input signal must take place to output. But in the case of high frequency input signals, diode capacitance affects the operation of circuit adversely and the signal gets attenuated (which means that, it passes through diode capacitance to ground).
What is formula for zener diode comparator?
A: There is no formula it is a comparison of the zener diode voltage to the other input when one exceed the other the comparator will change state on the output and decreasing will return to the previous state
How does the positive clamper works in electronic circuits?
A negative clamper circuit is considered. It shifts original input signal in a downward direction.While positive input is applied, diode is forward biased. The output voltage is Vo which is equal barrier potential of the diode. The capacitor is charged to V-Vo.When negative input cycle, diode does not conduct because it is reverse biased and the capacitor can not discharge very much because time constant (RC) choosen is high. Now output is sum of input voltage and capacitor voltage and it is equal to -(2V - Vo). Now peak to peak output voltage is difference of output voltages when positive and negative half cycles and it is equal to V-(-(2V - Vo)) or 2V.In negative clamper, input signal is pushed downward and positive peak of the output signal coincides with zero level.In positive clamper circuit, unlike in negative clamper circuit, diode is connected reversely.There is no change in connection of capacitor. But resistor is connected after diode. Positive clamping circuit shifts a input signal in upward direction. The output of this circuit shows that negative peak of signal coincides with zero level.
