چکیده
The design and implementation of a monolithic micro electro mechanical systems (MEMS)-based gas sensor virtual component is described. The gas sensor virtual component encloses the sensor and its associated analog circuitry into a digital shell so that all interface connections to the virtual component are digital. The system architecture supports an array of gas sensor elements. System response time is limited by the sensor and is complex. Example gas sensor characterization results are presented showing isothermal response to carbon monoxide molecules with detection sensitivity better than 100 nanomoles/mole. 2004 Elsevier Ltd.

Embedded Memory Test Strategies and Repair
The demand of self-testing proportionally increases with memory size in System on Chip (SoC). SoC architecture normally occupies the majority of its area by memories. Due to increase in density of embedded memories, there is a need of self-testing mechanism in SoC design. Therefore, this research study focuses on this problem and introduces a smooth solution for self-testing. In the proposed m...
