Abstract :
A new circuit of a magnetic (inductively tuned) RL-multivibrator is proposed. The circuit includes the transconductance amplifier with differential input and single output, and the RL-bridge circuit. The amplifier with limited output current is controlled by the bridge. The output current is distributed between the bridge branches. The resistive branch provides positive feedback and sets the threshold voltage. The inductor branch provides the delay in changing the direction of the amplifier output current. The circuit operation is described, the oscillation wave-forms are calculated, and the oscillation period is found. An example with bipolar transconductance amplifier was realized and tested.
