Abstract
Inventia se refera la un oscilator sinusoidal cu cuplaj prin transformator consti tuind o perfectionare a inventiei principale cu nr. 97764, caracterizat prin aceea ca un tranzistor cu efect de cîmp cu canal N, T1, este polarizat printr-un divizor rezistiv R1 si R2 într-un punct static în care curentul sau de drena scade la cresterea temperaturii, scazînd curentul de baza al unui tranzistor T2 oscilator, compensînd astfel cresterea cu temperatura a curentului de colector al tranzistorului T2. Oscilatorul rezolva problema stabilitatii cu temperatura si este destinat utilizarii în constructia radioreceptoarelor.The invention relates to a sinusoidal oscillator with a transformer coupling constituting a refinement of the main invention no. 97764, characterized in that a field effect transistor with channel N1, T1 is polarized by a resistive divider R1 and R2 at a static point in which its current or the drain decreases as the temperature increases, decreasing the base current of a transistor T2 oscillator, compensating for the increase in temperature of collector current of transistor T2. The oscillator solves the problem of temperature stability and is intended for use in the construction of radio receivers.
