This example shows a tunnel diode used to create an oscillator. Two resistors bias the diode into the negative-resistance region. When current begins to flow through the inductor, the voltage across the tunnel diode increases until it reaches the negative-resistance region of its curve. The inductor still has a positive voltage across it, which requires an increasing current, so the tunnel diode will not enter the negative-resistance region. Instead, it jumps to the right side of the curve. Now the inductor has a negative voltage, so the current slows down, and the tunnel diode traces the right side of its curve until it again reaches the negative-resistance region, after which the tunnel diode jumps to the left side of the curve and the cycle begins again.
