Push-pull RC-oscillator/multivibrator

The paper considers a new push-pull RC-oscillator/multivibrator. In the sinusoidal regime the circuit develops two counter-phase oscillations located at different DC levels. The DC level of the first oscillation is close to the power supply level, the DC level of the second oscillation is close to the ground. The transition from sinusoidal oscillations to the relaxation ones is achieved by changing the value of the capacitor present in the circuit, so that for small values of this capacitor the oscillations are sinusoidal; for large values the circuit develops relaxation oscillations. This transition is similar to that which exists in source-coupled oscillators/multivibrators. Indeed, this new oscillator may be considered as a version of source-coupled multivibrator using complementary gain stages.
