Electronic Amplification in the NDR Region

The aim of this chapter is to demonstrate that the GSC is capable of functioning as an active device, by sustaining oscillations in an inductor-capacitor LC circuit when biased in the NDR region. We first explain how this is possible by demonstrating a lambda diode as an oscillator and amplifier. In the process we derive and confirm equations for the oscillation frequency, the cut-off frequency and the gain of the amplifier.
