The example ultrasonic transducer includes a second membrane supported by the substrate. The second membrane is to exhibit a second frequency response different from the first frequency response when oscillated. The example ultrasonic transducer includes a third membrane supported by the substrate. The third membrane is to exhibit one of the second frequency response or a third frequency response different from the first frequency response and the second frequency response when oscillated.

Abstract: In described examples, a method of operating a charge pump includes a first control signal deactivating a first transistor, and the first control signal's logical complement activating a second transistor to reset the first transistor's DC bias voltage. The first control signal's logical complement deactivates the second transistor, and the first control signal provides a bias voltage to the first transistor to activate it, causing current to be transmitted from an input voltage to an output terminal. A second control signal deactivates a third transistor, and the second control signal's logical complement activates a fourth transistor to reset the second transistor's DC bias voltage. The second control signal's logical complement deactivates the fourth transistor, and the second control signal provides a bias voltage to the third transistor to activate it, causing current to be transmitted from the output terminal to a ground.

Abstract: A clock generator includes a hermetically sealed cavity and clock generation circuitry. A dipolar molecule that exhibits a quantum rotational state transition at a fixed frequency is disposed in the cavity. The clock generation circuitry is configured to generate an output clock signal based on the fixed frequency of the dipolar molecule. The clock generation circuitry includes a detector circuit, a multiplier, and reference oscillator control circuitry. The detector circuit is coupled to the cavity, and is configured to generate a detection signal representative of an amplitude of a signal at an output of the cavity. The multiplier is coupled to the detector circuit, and is configured to multiply the detection signal with a mixing signal to produce a derivative of the detection signal. The reference oscillator control circuitry is configured to set a frequency of a reference oscillator based on the derivative of the detection signal.

Abstract: An interposer acts as a buffer zone between a transceiver IC and a dielectric waveguide interconnect and establishes two well-defined reference planes that can be optimized independently. The interposer includes a block of material having: a first interface region to interface with an antenna coupled to an integrated circuit (IC); and a second interface region to interface to the dielectric waveguide. An interface waveguide is formed by a defined region positioned within the block of material between the first interface region and the second interface region.

Abstract: A high linearity phase interpolator (PI) is disclosed. A phase value parameter indicative of a desired phase difference between an output signal and an input clock signal edge may be provided by control logic. A first capacitor may be charged for a first period of time with a first current that is proportional to the phase value parameter to produce a first voltage on the capacitor that is proportional to the phase value parameter. The first capacitor may be further charged for a second period of time with a second current that has a constant value to form a voltage ramp offset by the first voltage. A reference voltage may be compared to the voltage ramp during the second period of time. The output signal may be asserted at a time when the voltage ramp equals the reference voltage.
