Zusammenfassung:Systems, devices, and methods are described herein for measuring an impedance of a DUT using an integrated impedance measurement device. A system includes a plurality of measurement circuits, a FFT processor, and a controller. The measurement circuits are coupled to the DUTs. Each measurement circuit is configured to generate a clock signal for a respective DUT, detect a voltage of the respective DUT, and generate first voltage related data using the clock signal and the voltage. The FFT processor is coupled to the measurement circuits. The FFT processor is configured to convert the first voltage related data into second voltage related data using a fast Fourier transform for each measurement circuit. The controller is configured to calculate an impedance using the second voltage related data for each measurement circuit and output the impedance to each DUT.
