Abstract: A track and hold circuit includes a signal input terminal, a clock input terminal, an output terminal, a transistor, and a bootstrapping circuit with a transformer. The transistor includes a source, a drain, and a gate, where the source is coupled to the signal input terminal, and the drain is coupled to the output terminal. The transformer includes a primary winding coupled to the clock input terminal, and a secondary winding. The secondary winding is coupled between the source and the gate to control a gate-source voltage of the transistor.

Abstract: In described examples, a circuit includes an analog frontend arranged to generate an analog stress compensating signal in response to a to-be-compensated analog signal and a first-axis stress sensing signal. The analog frontend can comprise a first precision component (e.g., 220) arranged on a piezoelectric material and arranged to generate the to-be-compensated analog signal that is affected by a stress exerted in the piezoelectric material and a directional stress sensor arranged on the piezoelectric material and coupled to the first precision component. The directional stress sensor is arranged to generate the first-axis sensing signal in response to a longitudinal resultant of a stress exerted in the piezoelectric material. A compensating circuit is arranged to generate a compensated output signal in response to the compensating analog signal and to-be-compensated analog signal.

Abstract: An apparatus is provided. In the apparatus, there is an antenna package and an integrated circuit (IC). A circuit trace assembly is secured to the IC. A coupler (with an antenna assembly and a high impedance surface (HIS)) is secured to the circuit trace assembly. An antenna assembly has a window region, a conductive region that substantially surrounds the window region, a circular patch antenna that is in communication with the IC, and an elliptical patch antenna that is located within the window region, that is extends over at least a portion of the circular patch antenna, and that is in communication with the circular patch antenna. The HIS substantially surrounds the antenna assembly.

Abstract: An ultrasonic detection circuit includes a transmitter circuit that provides excitation signals to an ultrasonic transducer during an excitation interval. A control circuit includes a port to receive a command. The control circuit controls the frequency and the duty cycle of the excitation signals of the transmitter circuit during the excitation interval. The control circuit generates a first excitation signal sequence of the excitation interval followed by a first monitoring period to receive a first echo signal in response to the command. The control circuit generates a second excitation signal sequence of the excitation interval followed by a second monitoring period to receive a second echo signal in response to the command. The control circuit outputs results via the port based on at least one of the first or second echo signals received.

Abstract: A circuit includes a serializer module that includes an input stage that samples an input signal to capture an edge location for each of the input signal in a given time frame. An edge encoder encodes the edge location for the input signal into a packet frame to specify where the edge location occurs in the given time frame for the input signal. A transmitter receives the packet frame from the edge decoder and converts the packet frame into a serial data stream. The transmitter communicates the edge location for the input signal via the serial data stream.

Abstract: Described examples include an integrated circuit including a receive portion to receive an encoded transmission on a line. The receive portion has: a wake mode in which the receiver is capable of receiving the encoded transmission; and a sleep mode in which the receiver is not capable of receiving the encoded transmission. A wakeup controller monitors the line for a wakeup signal and provides a signal to the receive portion to cause the receive portion to enter the wake mode when the wakeup controller receives the wakeup signal.

Abstract: Methods and systems for producing a low-power, low-phase noise oscillating signal using a self-injection locking oscillator. Preferred embodiments include, for example, producing, using an oscillator, a signal having a base frequency component, an Mth harmonic component and a Pth harmonic component, wherein M and P are selected integers and M>P>1; filtering said signal through one or more bandpass filters comprising at least two resonators, said filters having Q factor ≥5, said filters configured to pass said Mth and Pth harmonic components; multiplying said filtered Mth and Pth harmonic components together to produce a multiplied signal, and filtering said multiplied signal using a low pass filter to pass a difference between said filtered Mth and Pth harmonic components, said difference comprising a filtered beat frequency waveform; and injecting said filtered beat frequency waveform into said oscillator to thereby injection lock said signal to said filtered beat frequency waveform.
