Abstract
A circuit for measuring a parameter value by measuring the time required to charge a capacitor in a sensor RC circuit from a first to a second voltage includes a reference RC circuit whose capacitor is also charged between two voltage levels. The circuit is calibrated so that the time interval required to charge the reference capacitor may be used to improve the accuracy with which the parameter value is measured.
