INTEGRATED CIRCUIT PROCESS AND BIAS MONITORS AND RELATED METHODS

An integrated circuit device can include at least one oscillator stage having a current mirror circuit comprising first and second mirror transistors of a first conductivity type, and configured to mirror current on two mirror paths, at least one reference transistor of a second conductivity type having a source-drain path coupled to a first of the mirror paths, and a switching circuit coupled to a second of the mirror paths and configured to generate a transition in a stage output signal in response to a stage input signal received from another oscillator stage, wherein the channel lengths of the first and second mirror transistors are larger than that of the at least one reference transistor.
