1. QIE10 development Nov. 7, 2011: The first full-chip prototype was submitted to MOSIS. Output is 2-bit exponent (four ranges) and 6-bit mantissa (non-linear ADC). LSB = 3fC, maximum input = 330 pC (approx. 17-bit dynamic range). 3 modes of operation: Normal, Program, and Charge Inject. Both inverting and non-inverting inputs are available. Separate Frontend (integration) and Backend (digital output) 40 MHz clock inputs. Parallel LVDS digital outputs (mantissa, exponent, CapID, timing discriminator). Programmable via shift register: - Timing discriminator threshold - Pedestal DAC - Separate CapID pedestals on the lowest range - Force to fixed range operation for testing - Charge injection DAC (8 levels, covering 2 points on each of the 4 ranges) - Input bias levels (allows adjusting input impedance, etc.) Two previous prototype submissions were for the input amp/splitter and ADC sections. Both functioned as expected, so success is expected for this first full-chip prototype.
