WebIn the forward bias, it operates as a tunnel diode but its tunneling effect is much reduced as compared to tunnel diode. Otherwise, it operates as a normal P-N junction diode. In reverse bias, it operates as a Zener diode but the breakdown voltages are much lower. 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 …
