Measurement circuit for measuring the operating values, especially voltage, current or power of an IC, has a first circuit for measuring sequential states of a reference signal and a second circuit for measuring a clock signal

摘要

Circuit for determining at least an electrical value, especially a voltage, current or power value of an integrated circuit during its operation, has: a first measurement unit (5) for measuring and counting of sequential states of a reference signal (Ust) for generating an output voltage (Vint) of a voltage generator circuit (2) of the integrated circuit; a second measurement unit (6) for recording a clock signal (CK) and; an output circuit (7, 8) for output of a counter value of signal states for the reference signal and time reference signal with the aid of determining an electrical value. An Independent claim is made for a method for determining at least an electrical value, especially a voltage, current or power value of an integrated circuit during its operation.
