An oscillator circuit includes an electrical load, a first metal oxide semiconductor (MOS) devise, a second MOS device, and a negative feedback circuit. The electrical load is coupled between a first node and a second node. The first MOS device is coupled between the first node and a third node, and controls a first current flowing from the first node to the third node. The second MOS device is coupled between the second node and a fourth node, and controls a second current flowing from the second node to the fourth node. A positive feedback circuit is formed with the first and second MOS devices. The positive feedback circuit has inputs from the first and second nodes and outputs to the first and second MOS devices. The negative feedback circuit has inputs from the third and fourth nodes and outs to the first and second MOS devices. |
