Diode Resistance Levels (DC)

• operating point coordinates (Idq, Vdq)
• if there is a change in the operating point, it means there is a change in current through the diode or voltage across the diode or both, and when you change them the resistance will also change
• when we apply voltage to a circuit the result in an operating point will not change with time
• Q-point is derived from quiescent which means "still or varying"
• what will happen tot he DC Resistance when we increase the diode current?

  DC resistance will reduced
• DC resistance decreases with increase in current through the diode
• in reverse bias condition

  reverse saturation current is very low and because of that the DC resistance will be high
