APPLICATIONS OF SUPER-REGENERATIVE CIRCUITS USING TUNNEL-DIODES

Theoretical and experimental analyses were carried out to analyse the tunnel diode super-regenerative amplification and detection in linear and quasi-linear modes of operation. The dependencies of the diode ac conductance, stationary voltage and correction gain factors are invest igated as functions of different bias and input signal conditions. The gain in both modes of operation is computed at various circuit decrem ent and characteristic impedance values. Finally, the experimentally t raced output waveforms of the proposed super-regenerative detector pro ved that the system operates well in quasi-linear mode.
