Abstract
The apparatus includes: a ring oscillator including a set of cascaded current-starved inverters arranged in a ring; a set of field effect transistors (FETs) coupled in series with the set of cascaded current-starved inverters between an upper voltage rail and a lower voltage rail, respectively; a negative to absolute temperature (NTAT) current source configured to generate a NTAT current; and one or more current mirrors coupling the NTAT current source to the set of FETs.
