Abstract
An oscillator including, a parametric amplifier which has three branches at the terminals of a non-linear capacitor C(V). In the pump branch there is a negative resistance dipole (D) which is able to oscillate at frequency f.sub.p. One of the two other branches is matched to a resonant circuit (C.sub.s) exhibiting a high Q factor at frequency f.sub.s, and the other branch is matched to a load impedance, namely that of resonant circuit (C.sub.o) at frequency f.sub.o .multidot.(f.sub.o =f.sub.p -f.sub.s). A high level output signal f.sub.o is thus provided.
