Abstract:
1. An integrated circuit for supplying currents to a test apparatus for determining a voltage in the integrated circuit, the integrated circuit being operable in a test operating state including a first and a second test cycle, the integrated circuit comprising: a current generator circuit with a first input terminal for applying a reference voltage and a second input terminal for applying a voltage to be determined, the current generator circuit including a first control terminal for applying a first control signal and a second control terminal for applying a second control signal; an output terminal coupled to the test apparatus; and an interconnect for carrying a current, the interconnect coupling the current generator circuit to the output terminal, wherein the current generator circuit generates a first partial current upon application of the first control signal in the first test cycle of the test operating state and a second partial current upon application of the second control signal in the second test cycle of the test operating state, the current intensity of the first partial current being dependent on the voltage value of the reference voltage, and the current intensity of the second partial current being dependent on the voltage value of the said voltage to be determined, the interconnect supplying the first and second partial currents to the test apparatus for determining said voltage to be determined as a function of the reference voltage, the first partial current and the second partial current.
