Abstract: Systems, methods, and circuitries are provided for generating timing signals with a resonator-based open-loop oscillator circuitry. In one example, a system that generates a timing signal based on a target signal includes a plurality of oscillator units configured to generate a respective plurality of oscillator signals. Each oscillator unit includes a resonator that operates in an open-loop mode to generate a resonator signal having a resonator frequency. The resonator signal is used by core circuitry to generate a respective oscillator signal having a respective oscillator frequency. The resonator frequencies of the resonators in the plurality of oscillator units are different from one another. The system also includes a selector circuitry configured to select one of the plurality of oscillator units based on the target signal and provide a selected oscillator signal generated by the selected oscillator unit as the timing signal.

Abstract: Systems, methods, and circuitries enable selected signal components to be isolated in a feedback transmit signal that includes multiple signal components. In one example, a signal component cancellation system for a feedback receiver includes a transmit chain configured to transmit a transmit signal having at least two signal components with offset center frequencies. The system includes measurement circuitry configured to measure a received signal that results from feedback of the transmit signal and cancellation circuitry configured to cancel a selected signal component from the transmit signal to generate a cancellation signal. The system further includes subtraction circuitry configured to combine the cancellation signal with the measured received signal to generate a component signal corresponding to a contribution of the selected signal component to the received signal and provide the component signal to the feedback receiver.

Abstract: A tracker circuit configured to provide a variable supply voltage to a power amplifier (PA) circuit is disclosed. The tracker circuit includes a state machine circuit comprising a plurality of states mapped in accordance with transitions associated with a mapping scheme. In some embodiments, the plurality of states of the state machine circuit identify one or more operational modes associated with the tracker circuit, wherein at least one operational mode comprises one or more voltage levels respectively associated therewith. In some embodiments, the one or more operational modes includes at least two active operational modes. In some embodiments, a transition between the one or more operational modes of the tracker circuit is controlled by a digital selection signal received from a digital communication interface associated therewith.
