A certain nonlinear device has i D = v D 3 /8. Sketch iD versus vD to scale for vD ranging from -2 V to +2 V. Is this device a diode? Determine the dynamic resistance of the device and sketch it versus vD to scale for vD ranging from -2 V to +2 V.

for the given circuit, input voltage is AC(10,-10)v, R=2KQ , diode is ideal. what is the Vout in the positive and negative cycle ? just write numbers example: 5v,6v ..

Using ideal diodes (voltage drop across ideal diodes is zero) and resistors, construct a circuit that results in the following output vs. input voltage characteristics.

A silicon diode has an incremental resistance “R”. It is then connected in series with a resistor 25 ohms across a 25V source. If the voltage drop across the 25 ohm resistor is 10 V, what is the value of “R” ?

I need a more detailed explanation of this. I'm new to electronics. I don't know what is the Diode Current.

For the diode circuit to the right 8002 a V 1002 b 40mA 0.001V' a) To the left of points a and b, find the load-line relation by expressing the current, I with voltage, V. HINT: Write KCL equation for the circuit diagram and write I in terms of V from that KCL equation. This will be your load-line equation. b) Assume the diode has the following characteristic, using the load-line relation you found in (a), determine the operating voltage, V and current, I for the circuit. ip (mA) 20 15 10 5 Vp (V) 3.0 0.5 '1.0 1.5 2.0 2.5

Vi (t) = 10.sinwt Does not pass positive alternans when Volt input voltage is applied, only Design and explain two different circuits that pass negative alternans. Draw the input and output voltages. What are the types of these circuits? (Note: You can use the ideal diode approach)

In the circuit shown below. Let Vm-35 V and i-20 mA and VpQ -0.7 V: iD 3 kQ 0.8 kO Vmcos(@t)V For t Os, the current in the diode equals: Oa. 0 mA Ob. 4 mA Oc. 2 mA Od. 6 mA If t = T/4, then the current in the diode equals: Oa. 6.29 mA Ob. 5.03 mA Oc. 4,03 mA Od. 7.86 mA If t = T/2, then the current in the diode equals: Oa. 15.24 mA Ob. 13.24 mA Oc. 19.24 mA Od. 17.24 mA

After solving a circuit with ideal diodes (Vf=0), what check is necessary for diodes initially assumed to be on? Off? We must check to see that reverse voltage appears across all diodes assumed to be on, and we must check to see that forward current flows in diodes assumed to be off We must check to see that forward current flows in diodes assumed to be on, and we must check to see that reverse voltage appears across all diodes assumed to be off
