MEASURING A LEAKAGE CHARACTERISTIC OF A SIGNAL PATH

Abstract:

An example method measures a leakage characteristic of a signal path. The example method includes forcing a current onto the signal path; determining a parasitic capacitance of the signal path based on a rate of change of a voltage on the signal path resulting from the current; forcing a voltage onto the signal path for a period of time; and following the period of time, determining the leakage characteristic based on the parasitic capacitance and a rate of change in voltage on the signal path from the forced voltage.
