Abstract
The RC sensor circuit includes a driver circuit that includes an output configured to drive the RC sensor circuit to a drive voltage using a representative copy of a current that drives an electronic circuit line. The RC sensor circuit includes an integration capacitor. The integration capacitor is configured to integrate the representative copy of the current over a first time period to generate a first representative voltage and over a second time period to generate a second representative voltage. The RC sensor circuit includes a sampling circuit coupled to the integration capacitor. The sampling circuit is configured to determine a first sample voltage by sampling the first representative voltage and a second sample voltage by sampling the second representative voltage. A ratio of the first sample voltage and the second sample voltage is indicative of an RC time constant of the electronic circuit line.
