Abstract:
An oscillator circuit comprising:an electrical load coupled between a first node and a second node, the first node outputting a first oscillating voltage having a first peak voltage, and the second node outputting a second oscillating voltage having a second peak voltage; a first metal oxide semiconductor (MOS) device coupled between the first node and a third node, said first MOS device controlling a first current flowing from the first node to the third node; a second MOS device coupled between the second node and a fourth node, said second MOS device controlling a second current flowing from the second node to the fourth node, a positive feedback circuit being formed with said first and second MOS devices, the positive feedback circuit having inputs from the first and second nodes and outputs to said first and second MOS devices; and a negative feedback circuit having inputs from the third and fourth nodes and outputs to said first and second MOS devices.
