VERDI - Multi-channel Analog Readout for Radiation Detectors

VERDI is a multi-channel ASIC capable of reading out different type of radiation detectors (SDD, PMT, Si (Li) etc.) with both positive and negative signal polarities. The circuit includes 8 channels, each one composed by a Charge Sensitive Amplifier (CSA), a Shaping Amplifier, a Baseline Holder, a Peak Stretcher, and an output buffer.

Main Features

• Availability: bare die, QFP120, QFN80
• Physical size: 3.5 mm x 3.5 mm x ?? mm (bare die), 28 mm x 28 mm x 4 mm (QFP120), 12 mm x 12 mm x  0.8mm (QFN80)
• Reset: pulsed or continuous (with external zero-network)
• Mode: Normal, Low-Power (multiplexed output) or shut down
• Power consumption: 170 mW in low-power mode and 3mW in shut down mode

Applications

• Front-end JFET readout for radiation detector application
• Multi-element X and Gamma-ray detectors readout
• Nitrogen-cooled Ge and Si(Li) detectors, Silicon drift detectors (SDDs), Scintillation Detectors, Photomultipliers Tubes, etc.
