Abstract:
The present invention relates to an optical noise removal circuit, an optical receiver, and an optical chip. The optical noise removal circuit includes: a noise filter unit, where an input end of the noise filter unit receives an electrical signal coming from an photoelectric conversion unit, and the noise filter unit is configured to filter out a noise electrical signal, in the electrical signal, that is generated due to ambient light, and output a target pulse signal at an output end; and a comparison unit, where a first input end of the comparison unit is coupled to the output end of the noise filter unit to receive the target pulse signal, and the comparison unit is configured to output a digital signal based on comparison between the target pulse signal and a reference voltage. By implementing the present invention, quality of a received optical signal can be effectively improved.

Claim (Index 6):
The optical noise removal circuit according to  claim 5 , further comprising:\n a first divider resistor, wherein a first node of the first divider resistor is coupled to a supply voltage, a second node is grounded, an intermediate node is coupled to the second end of the coupling capacitor and the first input end of the comparison unit, and a voltage at the intermediate node is less than the reference voltage when there is no exposure to a signal light source and is greater than the reference voltage when there is exposure to a signal light source.
