Abstract
Current and future integrated systems demand
cost-effective test solutions. In response to that need, this work
presents a very compact mixed-signal test system. It performs the
characterization of the magnitude and phase responses over fre-
quency at multiple nodes of an analog circuit. The control inputs
and output of this system are digital, enabling the test of the analog
components in a system-on-chip (SoC) or system-in-package (SiP)
through a low-cost digital automatic test equipment. Robu
