Design of fully differential balanced photoelectric detection circuit for time domain interference system

Aiming at the problems of DC component and noise interference in the transimpedance photoelectric amplification detection circuit of the time domain interference system, the composition of the low-coherence time domain signal and the equivalent noise model of the transimpedance photoelectric amplification circuit are analyzed, and balanced detectors and fully differential photoelectricity are used. The detection circuit is combined to select and calculate the circuit device, complete the design of the fully differential balanced photoelectric detection circuit, and apply it to the signal processing of the time domain interference system of the biometer. Experimental results show that the designed circuit can effectively suppress the influence of DC component and noise, and significantly improve the quality of the system signal.
