Abstract
The present invention is directed to a system and method for measuring a current in an integrated circuit comprising measuring a first output count from a first voltage controlled oscillator (VCO) using a first measurement voltage, simultaneously measuring a second output count from a second VCO using a second measurement voltage, and calculating the current in the integrated circuit using a voltage proportional to a difference between the first and second output counts.
