A slope and amplitude controllable triangular-current generator for the injection of a broad-band PDN noise

Injection of the voltage noise into the PDN is so difficult due to the impedance mismatching between the PDN and connector. This paper proposed a triangular-current generator that can inject an artificial current waveform into the PDN and estimate the PDN noise. A slope and amplitude of triangular waveform manually varies depending upon the PDN impedance. Rogowski coils are implemented inside the generator to measure the current waveform.
