Abstract: The present disclosure is directed to a master-slave flip-flop memory circuit having a partial pass gate transistor at the input of the master latch. The partial pass gate transistor includes a pull-up clock enabled transistor for selectively coupling a high output of a test switch to the input of the master latch. The input of the master latch is also directly coupled to a low output of the test switch around the partial pass gate. In addition, a revised circuit layout is provided in which the master latch has three inverters. A first inverter is coupled to the input of the master latch. Second and third inverters are coupled to an output of the first inverter, with the second inverter having an output coupled to the input of the first inverter, and the third inverter having an output coupled to an output of the master latch. The first and second inverters are clock enabled, and the third inverter is reset enabled.

Abstract: The present disclosure provides supports for microfluidic die that allow for nozzles of the microfluidic die to be on a different plane or face a different direction from electrical contacts on the same support. This includes a rigid support having electrical contacts on a different side of the rigid support with respect to a direction of ejection of the nozzles, and a semi-flexible support or semi-rigid support that allow the electrical contacts to be moved with respect to a direction of ejection of the nozzles. The semi-flexible and semi-rigid supports allow the die to be up to and beyond a 90 degree angle with respect to a plane of the electrical contacts. The different supports allow for a variety of positions of the microfluidic die with respect to a position of the electrical contacts.

Abstract: An electronic device including a low dropout regulator having an output coupled to a first conduction terminal of a transistor, with a second conduction terminal of the transistor being coupled to an output node of the electronic device. A method for operating the device to switch into a power on mode includes: turning on the low dropout regulator, removing a DC bias from the second conduction terminal of the transistor, and turning on the transistor. A method for operating the device to switch into a power down mode includes: turning off the transistor, forming the DC bias at the second conduction terminal of the transistor, and turning off the low dropout regulator.

Abstract: The present disclosure is directed to a system that is configured to eject fluid vertically away from a thermal microfluidic die for use with scented oils or other fluids. The die is coupled to a rigid planar support board that separates the die from a reservoir of the fluid. The support board includes an opening that is lined with an inert liner that protects an interior surface of the support board from the fluid. The support board includes contact to an external power supply and contacts to the die on a first surface. The die is coupled to this first surface such that the second surface remains free of electrical connections.

Abstract: Data weighted averaging of a thermometric coded input signal is accomplished by controlling the operation of a crossbar switch matrix to generate a current cycle of a data weighted averaging output signal using a control signal generated in response to feedback of a previous cycle of the data weighted averaging output signal. The control signal specifies a bit location for a beginning logic transition of the data weighted averaging output signal in the current cycle based on detection of an ending logic transition of the data weighted averaging output signal in the previous cycle.

Abstract: A circuit includes a voltage converter converting source voltage to supply voltage at a first node as a function of a feedback voltage at a feedback node. A first output path is coupled between first and second node nodes. Feedback circuitry couples the second node to the feedback node when a voltage at the second node exceeds a first overvoltage, in a first mode of operation. The feedback circuitry couples the second node to the feedback node when the voltage at the second node exceeds a second overvoltage less than the first overvoltage, in a second mode of operation. Impedance circuitry is coupled between the first node and a third node and generates an auxiliary supply voltage and an auxiliary ground voltage when the circuit is in both the first and second modes, the auxiliary supply voltage being less than the supply voltage in both the first and second modes.

Abstract: Disclosed herein is a test apparatus for a device under test. The test apparatus includes a voltage translator coupled to receive test data from the device under test, over a physical interface, using one of a plurality of I/O standards, with the voltage translator being capable of communication using each of the plurality of I/O standards. A programmable interface is configured to receive the test data from the voltage translator. A bit error rate determination circuit is configured to receive the test data from the programmable interface and to determine a bit error rate of reception of the test data over the physical interface based upon a comparison of the test data to check data.

Abstract: A low dropout regulator produces output at an intermediate node. A resistive divider is coupled between the intermediate node and ground and provides a feedback signal to the low dropout regulator. A transistor has a first conduction terminal coupled to the intermediate node and a second conduction terminal coupled to an output node. A first impedance is coupled to the output node, a first switch selectively couples the first impedance to a supply node, a second impedance coupled to the output node, and a second switch selectively couples the second impedance to a ground node. Control circuitry is coupled to the control terminal of the transistor and to control terminals of the first and second switches. The control circuitry switches the electronic device to a power down mode by turning off transistor, closing the first and second switches, and turning off the low dropout regulator.

Abstract: The state of charge of a rechargeable battery is determined by calculating the DC impedance of the battery. The impedance is calculated by: performing a two different constant current discharges of the battery at a first and second C-rates, respectively; measuring the voltage and current during the interval of each constant current discharge and calculating the amount of charge extracted from the battery up to a point where the battery voltage drops to a threshold value; calculating the state of charge of the battery; and calculating the DC impedance of the battery as a function of the difference between the battery voltages and discharge currents for the two different discharges.

Abstract: Video encoders and decoders and video encoding and decoding methods are provided. A video encoder includes an input buffer configured to receive a video data stream and to supply current frame data, a frame buffer configured to store reconstructed frame data, and an encoder circuit configured to read reference frame data from the frame buffer, to encode the current frame data received from the input buffer using the reference frame data and to write the reconstructed frame data to the frame buffer. The encoder circuit may be configured to write the reconstructed frame data by overwriting the reference frame data in the frame buffer.
