Abstract
An integrated oscillator circuit has a plurality oscillator stages including a first oscillator stage, an odd number of intermediate oscillator stages, and a last oscillator stage arranged in series. Each of the oscillator stages has a reverse-biased diode device and a transistor coupled in series between a power supply and a ground. Each diode device has an anode and a cathode, and each transistor has a control terminal for controlling a current flow from a first terminal to a second terminal. In each oscillator stage, the anode of the diode is coupled to the first terminal of the transistor at an internal node. The control terminal of the transistor in each oscillator stage is coupled to the internal node of a proceeding oscillator stage. Further, the control terminal of the transistor in the first oscillator stage is coupled to the internal node of the last oscillator stage.
