A method for compensating signal nonlinearities includes generating a local oscillator (LO) signal and performing phase modulation of the LO signal to generate a phase-modulated LO signal. The phase modulation is based on applying at least one digital-to-time converter (DTC) code of a plurality of DTC codes to a rising edge signal portion and a falling edge signal portion associated with the LO signal. Nonlinearities associated with the rising edge signal portion and the falling edge signal portion are determined. The at least one DTC code is adjusted based on the nonlinearities.

Digital-to-time converter (DTC) non-linearity predistortion

An electronic circuitry is proposed. The electronic circuitry comprises a directional coupler comprising a first port configured to receive an input signal from a signal source, a second port configured to output the input signal for transmission to a load, a third port configured to output a forward signal based on the input signal, and a fourth port configured to output a reverse signal based on a reflection of the input signal received at the second port. The electronic circuitry further comprises a Time-to-Digital converter, TDC, coupled to the third port and the fourth port. The TDC is configured to determine a phase difference between the forward signal and the reverse signal.
