A distributive photonic monobit analog-to-digital converter includes a plurality of signal processing chains configured to receive a corresponding plurality of analog input electrical signals. Each processing chain includes an incoherent optical source configured to generate an optical noise signal, an optical modulator configured to modulate an analog input electrical signal of the plurality of analog input electrical signals onto an input optical signal to generate an optical modulated signal, a coupler configured to couple the optical modulated signal with the optical noise signal to generate a coupled signal, a photodetector configured to generate a phase difference between the optical modulated signal and the optical noise signal using the coupled signal, and a limiter configured to output a decision signal based on the phase difference and using a clock signal. A multi-phase clock generator is configured to generate the clock signal for each of the plurality of signal processing chains.
