WebBut this cannot create a -0.1V output at the bottom of D2; that is nonsense because it is outside of our supply range. 0.5V is not enough to forward bias D2, and so the output is at 0V, pulled to ground by R2, which has almost no current flowing across it … WebThis external bias voltage is designed as V BIAS. The resistor limits the forward current to a value that will not damage the diode. Notice that the negative side V BIAS is connected to the n region of the diode and the positive side is connected to the p region. This is one requirement for forwarding bias. A requirement for forward bias.
