Innovative Practices Session at VLSI Test Symposium 2024: Analog Testing Technologies for Digital Exploding Society

Digital technologies are rapidly prevailing in our society, and there the performance of analog circuits is progressing and their market amount is growing steadily. We have experienced that in many cases analog parts may be small compared to digital ones, but analog ones are troublesome. Testing of analog circuits plays a crucial role in achieving both reliability and low cost such as in computer, Internet, AI, IoT and automotive systems. Also, in ATE systems, analog parts are key. Analog testing is a challenge including circuit design, signal processing algorithms and measurement methods/systems.This session will discuss analog testing related issues with three talks by researchers from industry. The first talk introduces a state-of-art low jitter 1GHz crystal oscillator by an ATE manufacturer. The second one explains a time measurement BOST using a successive approximation register time-to-digital converter (SAR TDC) with fine resolution by a semiconductor company. The third one is a proposal of an ADC diagnosis method using obtained self-calibration parameters, by an ADC design researcher.
