Resonator-based open-loop timing signal generation

A transceiver configured to transmit or receive signals having a target frequency, comprising:

• an open-loop oscillator circuitry configured to generate a local oscillator (LO) signal having an LO frequency based on the target frequency;
• and
• a baseband signal compensation circuitry comprising:
• a frequency measurement circuitry configured to measure the LO frequency of the LO signal;
• phase correction circuitry configured to adjust a phase of a baseband signal based on a difference between the measured frequency and the target frequency to generate a rotated baseband signal;
• frequency adaptation circuitry configured to adapt a frequency of the rotated baseband signal to generate a compensated baseband signal;
• and
• a modulator configured to modulate the compensated baseband signal using the LO signal.

A method to generate a timing signal based on a target frequency, comprising:

• generating a plurality of oscillator signals with a respective plurality of resonators operating in an open-loop mode;
• selecting one of the oscillator signals based on the target frequency;
• and
• providing the selected oscillator signal as the timing signal.
