Abstract

PURPOSE:To obtain the outputs of opposite polarities to each other with a constant amplitude, by connecting in common to collectors of two transistors, earthing the emitters via a capacitor and connecting the both ends of an oscilating coil to the bases of the transistors, respectively. CONSTITUTION:The collectors and connected in common for NPN transistors TRQ1 and TRQ2 and then connected to a power supply terminal, respectively. The base of the TRQ1 is connected to the emitter of the TRQ1 via a capacitor C2, and the emitter is earthed via a resistance R1 and a capacitor C3 which are connected in parallel. An end of an oscillating coil L is connected to the base of the TRQ1 via a coupling capacitor C1, and the other end of the coil L is connected to the base of the TRQ2 via a coupling capacitor C4.
