| Keywords: Negative resistance oscillator circuit VCNR.svg Negative resistance oscillator circuit used with voltage controlled negative differential resistance VCNR devices VCNRs require low impedance DC bias and are stable for load impedances less than their differential resistance r so they are called short-circuit stable devices Therefore they are often used in circuits like this with a series voltage source V<sub>bias</sub> to bias the device and a parallel resonant circuit LC as a load The parallel resonant circuit has a high impedance at its resonant frequency but a low impedance at all other frequencies so the circuit will be unstable and oscillate only at the resonant frequency 2012-12-26 16 06 03 own Chetvorno cc-zero Uploaded with UploadWizard Negative resistance | ||||
