ABSTRACT:
An oscillator including a non-inverting amplifier coupled in series with an inverting amplifier. A first feedback network couples the output from the non-inverting amplifier to the input of that amplifier by way of a capacitor C. A second feedback network couples the output of the inverting amplifier to the input of the non-inverting amplifier by way of a series connected resistor R, and includes a capacitor coupled between the input of that non-inverting amplifier and a reference potential. A third feedback network generates a feedback signal proportional to the difference between the average voltage at the output of the non-inverting amplifier and the average voltage at the output terminal of the inverting amplifier, and couples that feedback signal to the input of the inverting amplifier.
