摘要： Specific ionic interactions with a sensing material that is electrically coupled with the floating gate of a floating gate-based ion sensitive field effect transistor (FGISFET) may be used to sense a target material. For example, an FGISFET can use (e.g., previously demonstrated) ionic interaction-based sensing techniques with the floating gate of floating gate field effect transistors. The floating gate can serves as a probe and an interface to convert chemical and/or biological signals to electrical signals, which can be measured by monitoring the change in the device's threshold voltage, VT.

摘要： An integrated circuit programmable multiplexer that reduces sub-threshold leakage current in deep sub-micron technology. The multiplexer uses a plurality of transistor stages, wherein each transistor of a subsequent stage is connected to at least two transistors of a prior stage, such that each transistor is in series with at least one other transistor. Transistors that are not part of the signal path through the multiplexer are deactivated, wherein a series of two or more deactivated transistors have significantly less sub-threshold leakage current than a single deactivated transistor. Configuration memory cells that store and communicate control signals to the multiplexer transistors are also connected to a low-voltage power supply when the multiplexer is not in use to reduce leakage current through the memory cells.

摘要： A programmable interface circuit is disclosed, in accordance with one embodiment, which supports differential and single-ended signaling. For example, an input buffer within the programmable interface circuit is configurable to receive differential signals or single-ended signals. A multiplexer provides the appropriate reference signal to the input buffer, when configured to receive single-ended signals, by selecting the reference signal from a plurality of reference buses. The multiplexer, along with a capacitor, may also provide lowpass filtering of the reference signal. Furthermore, an output buffer may be configurable utilizing techniques similar to that described for the input buffer.

摘要： A silicon interposer has a plurality of conductive vias extending from a first side of a silicon substrate to an opposite side of the silicon substrate. A plurality of first side scan chain links are disposed on the first side of the silicon substrate. Each scan chain link electrically connects two conducting vias of the plurality of the conductive vias together. In some cases, a test fixture connects the opposite side of the conductive vias together and continuity or resistance is measured. In other cases, scan chain links are formed on the opposite side of the wafer to form a scan chain, which is electronically tested.
