Abstract
The invention concerns a detection device including a photodiode (Ph) designed to capture a luminous signal to transform it into a current (Iph) and including first and second terminals, a transimpedance amplifier circuit connected between the first terminal and the second terminal of the photodiode (Ph) and designed to amplify the current (Iph) coming from the photodiode (Ph). The transimpedance amplifier circuit includes a plurality of operational amplifiers (AOP1, AOP2, AOP3) connected in parallel and a gain resistor (R) common to all the connected amplifiers.
