Abstract
Circuitry for characterising a test impedance of a test load, the test load coupled between a sense node and a first driver node, the circuitry comprising: driver circuitry configured to apply a time-varying test stimulus between the first driver node and a second driver node, the test stimulus varied in step changes at a one or more of signal events; a reference load coupled between the second driver node and the sense node, the reference load having a programmable impedance comprising: a first programmable capacitance; a programmable resistance connected in series with the first programmable capacitance to form a series combination; and a first integrator configured to integrate a sense voltage derived from the sense node to generate a first integrated signal.
