Abstract:
1. A switching circuit test arrangement for determining the operativeness of an electronic switching circuit, the switching circuit comprising: a test signal input terminal for application of a test input signal; a test signal output terminal, at which a test output signal can be provided; a multiplicity of test circuit blocks, each test circuit block having at least one first sub-circuit block and at least one second sub-circuit block, the test circuit blocks being connected between the test signal input terminal and the test signal output terminal, such that the functionality of the test circuit blocks can be tested by means of the test input signal, wherein the at least one first sub-circuit block includes at least one first field effect transistor having a gate insulation layer, wherein the at least one second sub-circuit block includes at least one second field effect transistor having a gate insulation layer, and wherein the gate insulation layer of the first field effect transistor is thicker than the gate insulation layer of the second field effect transistor, such that the at least one first field effect transistor is configured as a driver of the second field effect transistor and further comprising a test input signal generating unit for generating a test input signal to be fed to the test signal input terminal; a test output signal evaluation unit for determining the operativeness of the electronic switching circuit; and an operating voltage source for providing an operating voltage.
