Resistance measurement and current control

A technique for measuring the resistance of a resistive element 4 in the presence of a series diode 10 is provided. By supplying three different currents I1, I2, I3 and measuring corresponding voltages V1, V2, V3 across the resistive element 4 and diode 10, the voltages can be combined to at least p...

Summary:A technique for measuring the resistance of a resistive element 4 in the presence of a series diode 10 is provided. By supplying three different currents I1, I2, I3 and measuring corresponding voltages V1, V2, V3 across the resistive element 4 and diode 10, the voltages can be combined to at least partially eliminate an error in the measured resistance of the resistive element 4 caused by a voltage drop across the diode 10. A technique for current control in an array of resistive elements 60 is also described in which a column of resistive elements 60 is provided with two or more current sources 70, 72 switched so that while one current source 70 is providing current to the column line 66 corresponding to a selected resistive element 60, another current source 72 has its amount of current adjusted.
