    Abstract: A low-leakage circuit includes first, second, and third transistors, which may be P-channel or N-channel FETs. The first transistor provides an output current when enabled and presents low leakage current when disabled. The second transistor enables or disables the first transistor. The third transistor connects or isolates the first transistor to/from a predetermined voltage (e.g., VDD or VSS). The circuit may further include a pass transistor that provides a reference voltage to the source of the first transistor when the first transistor is disabled. In an ON state, the first transistor provides the output current, and the second and third transistors do not impact performance. In an OFF state, the second and third transistors are used to provide appropriate voltages to the first transistor to place it in a low-leakage state. The first, second, and third transistors may be used for a low-leakage current source within a current mirror, an amplifier stage, and so on.

    Abstract: Techniques for compensating for propagation delay differences between signals distributed within a logic circuit. A delay matching circuit mimics the internal clock-to-Q delay produced by a flop. The delay matching circuit is placed in the propagation path of an original signal, such as a clock signal, to be redistributed. In general, the delay matching circuit may include a propagation gate multiplexer have a particular configuration. The delay matching circuit imposes a delay substantially equal to the clock-to-Q delay experienced by divided versions of the original signal. In this manner, the delay matching circuit ensures that the rising and falling edges of the original signal and the divided signal are in substantial alignment, enabling synchronous operation. Hence, the delay matching circuit is capable of synchronizing the redistributed and divided signals.

    Abstract: The single-use disposable spectrophotometer described in this disclosure can measure one or more blood chemistry analytes from a drop of whole blood. A passive filtration system takes whole blood and delivers plasma along with a dissolved reporter molecule to one or more spectrophotometers which can operate with narrow band optical spectrum centered on an optical detection frequency. The spectrophotometer detects the changes in absorption of the plasma as a result of a chemistry reaction to determine the concentration or activity of one or more analytes.

    Abstract: A PLL includes a charge pump, a loop filter, a VCO, and a calibration unit. The calibration unit performs coarse tuning to select one or multiple frequency ranges, performs fine tuning to determine an initial control voltage that puts the VCO near a desired operating frequency, measures the VCO gain at different control voltages, and derives VCO gain compensation values for the different control voltages. The calibration unit also pre-charges the loop filter to the initial control voltage to shorten acquisition time, enables the loop filter to drive the VCO to lock to the desired operating frequency, and performs VCO gain compensation during normal operation. For VCO gain compensation, the calibration unit measures the control voltage, obtains the VCO gain compensation value for the measured control voltage, and adjusts the gain of at least one circuit block (e.g., the charge pump) to account for variation in the VCO gain.

    Abstract: A stand-alone assay system for POC IVD that is fast, easy to use, inexpensive and delivers laboratory quality results for one or more target analytes from a small volume of unprocessed aqueous sample is disclosed. The stand-alone assay system is a disposable digital device. The stand-alone assay system integrates a sampling system that relies on users swiping a lanced finger containing an unprocessed aqueous sample such as whole blood across a sample inlet to transfer or deposit the unprocessed aqueous sample on to a membrane filter or into a capillary. The system can have a planarized testing surface on which retained magnetic particles are sensed.
