Abstract
First and second NPN transistors are direct connected in an astable multivibrator configuration. Each collector is connected to the positive terminal of a DC power source through series connected diodes. A resistor, which is selected to control the amplitude of oscillation, is connected between the collectors. The frequency of oscillation is controlled by a frequency determining component which is connected between the emitters of said transistors. The emitters are connected to current sources.
