Abstract (en)
[origin: WO9400912A1] The aim of the invention is to provide an oscillator circuit which generates high-frequency output signals and can be controlled by a d.c. signal. The invention calls for a first stage (10), which oscillates at substantially the same frequency, to be connected in series with a second stage (20) which includes a variable-capacitance diode. The preferred use of the invention is in double converters for processing TV signals.
