US Patent 12088441 Systems and methods for real-time frequency shift detection

Systems and methods disclosed herein include a correction circuit. The correction circuit may include signal conditioning circuitry that is configured to condition a received reference signal. The correction circuit may include a filter that is configured to filter the conditioned signal received from the signal conditioning circuitry. The correction circuit may include phase detector circuitry that is configured to generate at least one output signal based on measuring a phase shift between a received plurality of input signals. At least one of the plurality of input signals may include the conditioned signal received from the filter.
