Abstract
There is a disclosed an oscillator for generating a periodic signal, comprising a transistor and two electro-magnetically coupled inductors in positive feedback configuration, one of the inductors is connected to the drain or gate of the transistor, and the other being connected to the source to maintain the same phase of the two voltages at the two nodes. Two or more of such single ended oscillators can be connected together to form a differential oscillator, and the invention can be generalized by the use of any active device and not just transistors.
