An ASIC with a Low Power Multichannel ADC for Energy and Timing Measurements

Densely packed gamma-ray imaging and spectroscopy instruments employ high performance multichannel electronics which occupy large volume and dissipate excessive heat- Therefore, a low power application specific integrated circuit (ASIC) incorporating multiple channels of digitizers and post processing electronics is of critical importance for nuclear physics (NP) instrumentation- Microchip Corp- proposes to develop an ASIC with a novel 12-bit 32 channel 200MSps ADC to provide digital peak detection capabilities for multichannel radiation detector systems- The ASIC will accept random pulse data on 32 input channels producing a single digital output per channel having peak amplitude, timing, and channel address information- This ASIC will offer high channel density and low power consumption that cannot be achieved in systems based on off-the-shelf components- The integrated 32-channel ADC will be able to operate in two modes- In the first mode of operation, the ASIC will support applications in detector instruments- To increase the commercialization potential, the ASIC will also support a second mode of operation when the ADC data is directly supplied to the serial outputs through the JESD204B standard compliant interface-
