Стабільний діапазонний генератор гармонічних коливань

Abstract

The proposed stable oscillator with signals within a frequency range contains a direct voltage source, four bipolar transistors, three resistors, two capacitors, and additionally, the second direct voltage source. The first terminal of the first voltage source is connected to the first terminal of the first resistor. The second terminal of the first resistor is connected to the collector of the first transistor and the base of the second transistor. The collector of the second transistor is connected to the first terminal of the second resistor, the first terminal of the first capacitor, the emitter of the fourth transistor, and the first output of the generator. The second terminal of the second resistor is connected to the collector of the third transistor and the bases of the first and the third transistors. The second terminal of the first capacitor is connected to the base of the fourth transistor and the first terminal of the third resistor. The second terminal of the third resistor is connected to the collector of the fourth transistor, the first terminal of the second capacitor, and the first terminal of the second voltage source. The second terminal of the first voltage source is connected to the emitters of the first, second, and third transistors, the second terminal of the second capacitor, the second terminal of the second voltage source, and the second output of the generator, forming the common point of the circuit of the generator.
