| titleOfInvention | A kind of detection circuit based on photodiode |
| abstract | The utility model relates to photodiode technologies fields, disclose a kind of detection circuit based on photodiode.Including control unit and receiving unit, control unit includes the controllable light source that at least one is used to issue optical signal, and receiving unit includes preamplifier circuit and several photodiodes for being used to receive optical signal；All photodiode plus earths, cathode is in parallel, and cathode, which is connected in parallel, a little to be connect with preamplifier circuit；Preamplifier circuit includes the first operational amplifier, and the cathode of the first operational amplifier inverting input terminal and photodiode is connected in parallel a connection；First operational amplifier non-inverting input terminal ground connection, the first operational amplifier inverting input terminal are connect by feedback resistance with the first operational amplifier output terminal.The utility model greatly simplifies circuit structure, reduces necessary element, effectively saves cost and space, while keeping original detection accuracy. |
