| Popis: | This work describes a multi-channel electronic board for the acquisition and digitalization of current signals in the range from femto-amperes up to the tens of micro-amperes suitable in a wide range of applications for the readout of photodiodes. The electronic board includes a sensor bias generation circuit capable to drive large capacitive loads with good noise performances. The system also has user-congurable general-purpose pins for the control and actuation of external subsystems and provides both USB and UART interfaces for data transfer. The system features low power consumption in order to enable point-of-care applications. |
