Abstract: Frequency and phase of an output signal is adjusted to track an input signal. A control signal is adjusted to control a frequency of an oscillating signal from which the output signal is derived. In some aspects the frequency of the oscillating signal is adjusted by reconfiguration of reactive circuits coupled to an oscillator circuit. Phase of the output signal may be adjusted based on comparison of the oscillating signal with an adjustable threshold. For example, the adjustable threshold may comprise an adjustable bias signal for a transistor circuit whereby the oscillating signal is provided as an input to the transistor circuit and the output of the transistor circuit provides the output signal.

Abstract: An apparatus for wireless communications is disclosed including a super regenerative receiver adapted to receive an incoming signal from a remote apparatus, and a circuit adapted to at least partially determine the distance to the remote apparatus based on the incoming signal. The super regenerative receiver may be configured for relatively high sensitivity to allow the distance measurement circuit to discern the line-of-sight (LOS) portion of the incoming signal from the non-LOS portion thereof. Using the time of the LOS portion of the incoming signal, the circuit is able to more accurately determine the distance to the remote apparatus. By sending a signal to the remote apparatus, and receiving a response signal from the remote apparatus, the circuit may determine the distance to the remote apparatus from the respective times of the transmission and reception of the signals.

Abstract: Frequency of an oscillating signal is temporarily adjusted to adjust frequency and/or phase of an output signal. For example, the frequency of the oscillating signal may be adjusted for a very short period of time to adjust the phase of the output signal. In addition, the frequency of the oscillating signal may be temporarily adjusted in a repeated manner to adjust the effective frequency of the output signal. In some aspects the frequency of the oscillating signal is adjusted by reconfiguration of reactive circuits associated with an oscillator circuit.
