Test cost is becoming a more and more significant portion of the cost structure in advanced semiconductor products. To address this issue, we propose HOY - a novel wireless test system with enhanced embedded test features. We present the concept, architecture, and test flow for future semiconductor products tested by HOY. Necessary technologies for the(More)
A time-domain analog-to-digital (ADC) based on a domino delay line for high-speed applications is presented. The structure is mainly built on digital blocks and is compatible with digital nanometer processes. The domino delay line consists of enhanced delay units and parallel reset for reducing the propagation delay. Dual-mode operation including a Nyquist(More)
This work presents miniaturized CMOS (complementary metal oxide semiconductor) capacitive sensors for detection of the neurotransmitter dopamine (DA) down to the sub-fM range. Sensing resolution is significantly enhanced by monolithic sensor integration to reduce the parasitic effect and the use of sub-μm interdigitated microelectrodes as the sensing(More)
Physiologically, the thoracic (THO) and abdominal (ABD) movement signals, captured using wearable piezo-electric bands, provide information about various types of apnea, including central sleep apnea (CSA) and obstructive sleep apnea (OSA). However, the use of piezo-electric wearables in detecting sleep apnea events has been seldom explored in the(More)
