We present a measurement module that computes the charge from the transient supply current and provides a digital value of this magnitude. The module is constructed to provide a feasible implementation of transient current testing in production-like environments. Experimental results demonstrate up to 1 GHz analog bandwidth, while the effective test speed is mainly determined by the A/D converter included in the module.
