Energy Monitor

An 8-channel charge-to-digital converter with embedded voltage bias. Laser pulse energy can be monitored with a photodiode and the Energy Monitor by integrating the photocurrent. In this application, only one coaxial cable is required for connecting the photodiode as the reverse bias voltage is embedded in each channel. The Energy Monitor also can be applied in the field of high-energy physics experiments for integrating particle charges.
