Abstract
The invention refers to a sinusoidal oscillator with coupling through a transformer and consists of an improvement of the main invention no. 97764. An N channel field effect transistor (T1) is polarized through resistive divisors (R1 and R2) in a static point where its drain current decreases with the increasing temperature, decreasing the base current of an oscillating transistor (T2), thus compensating the increase with the temperature of the collector current of the transistor (T2).The oscillator solves the problem of stability with the temperature and it is applicable in the construction of radio receivers.<IMAGE>
