Figure 2
Block diagram of the ASIC electronics associated with each pixel. Low-noise CMOS electronics provide a means to window an energy of interest and count photons into either of two digital counters. The thresholds of the `low'and `high' comparators (CMPLo, CMPHi) can be individually calibrated by data latched into a 3-bit static memory (SRAM) and applied by the digital-to-analog converters (DAC).
