This invention discloses an I-V conversion circuit resistant to strong light interference, relating to the field of
integrated circuit technology. It includes an
infrared photodiode VD, resistors R1 and R2, an
amplifier AMP, and PMOS transistors M1, M2, and C. The invention also discloses an I-V conversion circuit resistant to strong light interference, including an
infrared photodiode VD, resistors R1 and R2, amplifiers AMP1 and AMP2, NMOS transistors M1, M2, and M3, and
capacitor C. Furthermore, the invention discloses an
infrared receiving
chip incorporating the aforementioned I-V conversion circuit resistant to strong light interference. Under strong light conditions, this invention prevents the output
voltage OUT from continuously increasing, effectively receiving, identifying, and amplifying the input
signal, thus improving
signal quality and reducing
distortion.
