An oscillator constructed using complementary transistors in a push-pull configuration employs means to vary at least one base voltage divider resistor to adjust the working points of the complementary transistors and an additional transistor having its emitter-collector circuit connected between the bases of the complementary transistors, which additional transistor has its conduction controlled by the output signal of the oscillator so that the collector-emitter region thereof is progressively driven toward lower and lower resistance in response to increasing amplitude of oscillation. |
