Digitally-Assisted Analog Test Technology : Analog Circuit Test Technology in Nano-CMOS Era

Abstract

This paper reviews current production testing issues for analog and mixed-signal SoC, and discusses the following: (i) Digitally-assisted analog technology prevails in mixed-signal SoC with fine CMOS which uses digital-rich architecture, digital self-calibration and error correction, and we consider their effective production testing. (ii) Mixed-signal SoCs frequently incorporate digital resources such as DSP cores and memory. We discuss how such resources can be utilized to simplify production testing of the analog RF circuitry in the SoC.
