| Keywords: Negative resistance oscillator block diagram.svg negative resistance electronic oscillator illustrating the reference plane analysis method The circuit consists of a differential negative resistance device such as a Gunn diode or magnetron tube connected to a resonator such as a LC circuit dielectric resonator or cavity resonator To determine the frequency and amplitude of oscillation the circuit is thought of as divided by a plane <font color red > red </font> into two parts the negative resistance device and the resonator and load The complex impedance looking into each part Z<sub>N</sub> jω and Z<sub>L</sub> jω is calculated The circuit will oscillate at the freqency ω and amplitude at which Z<sub>N</sub> -Z<sub>L</sub> Alternately the reflection coefficient Γ can be used The circuit will oscillate when Γ<sub>N</sub>Γ<sub>L</sub> 1 2012-12-20 05 54 07 own Chetvorno cc-zero Uploaded with UploadWizard Negative resistance | ||||
