Abstract

The invention provides a temperature collection circuit and light receiving module and relates to the technical field of temperature collection. The temperature collection circuit comprises a temperature sensor, a signal amplification circuit, a temperature compensation circuit and a data storage device, wherein the temperature sensor is arranged on a trans-impedance amplifier so as to sense temperature of the trans-impedance amplifier and then generate electric signals; an input end of the signal amplification circuit is connected with an output end of the temperature sensor, and therefore the electric signals can be amplified; an input end of the temperature compensation circuit is connected with an output end of the signal amplification circuit, and therefore the amplified electric signals can be compensated; an input end of the data storage device is connected with an output end of the temperature compensation circuit, and therefore the compensated electric signals can be stored. Via the above arrangement, collected and stored temperature data can be used as a reference factor for heat dissipation of the trans-impedance amplifier, and therefore a problem that interference withwork of the trans-impedance amplifier is caused because unreasonable heat dissipation operation is performed on the trans-impedance amplifier based conventional technologies can be solved.

Description

technical field [0001] The invention relates to the technical field of temperature acquisition, in particular to a temperature acquisition circuit and a light receiving module. Background technique [0002] With the deepening of signal diversification, people have higher and higher requirements for the transmission of audio, video and other information. In the field of communication, optical communication is widely used in various industries due to its characteristics of large transmission capacity, high security performance and good anti-interference performance. In optical communication technology, it generally includes an optical transmitting end, an optical receiving end, and an optical cable connecting the optical transmitting end and the optical receiving end. Among them, in the light receiving end, there is a problem that the amplitude of the electrical signal generated by the photodetector inducting the light signal is generally small, so it is difficult to process ...
