An Optoelectronic Chip with excellent orthogonality for Encoder Application

This paper proposes a unique optoelectronic chip, which is specifically applied to the Encoder. Unlike traditional detectors, the author arranges and arranges the detectors according to certain rules, and combines the detectors with op-amp circuits. The results of the simulation of the chip layout show that the output signal of the chip exhibits excellent orthogonality, and the amplifier gain are greater than 90 dB with 400k Hz response frequency. The photoelectric chip can restore the measured light signal to the utmost.
