ABSTRACT:
An electronic circuit and method to determine a resistance value of a resistive element. The circuit includes a current source coupled in series with the resistive element. The current source is configured to force a predetermined value of current through the resistive element and includes a transconducting device coupled to the current source. The transconducting device is configured to sense a voltage across the resistive element and transform the voltage into an output current of the transconducting device such that the output current is not dependent upon any other terminal voltages of the transconducting device.
