Abstract
A programmable load circuit operable to generate a plurality of test signals is described. The programmable load circuit comprises a diode bridge coupled between an input and an output. The diode bridge compares the voltage on the input to the voltage on the output. The programmable load circuit also comprises a plurality of current sources. A first set of the plurality of current sources are coupled to intermediate nodes of the diode bridge. Additionally, the programmable load circuit comprises a switching circuit coupled between the intermediate nodes of the diode bridge and a second set of the plurality of current sources. Furthermore, the programmable load circuit also comprises a load regulator coupled to the output and the intermediate nodes of the diode bridge. The load regulator is configured to reduce leakage current on the output.
