Abstract :
A four-channel multi-function CMOS integrated circuit designated as the Mondo Chip has been developed for the PHENIX electromagnetic calorimeter. Each channel of the Mondo Chip has an energy measurement circuit with a 14-bit dynamic range, a timing measurement circuit with a range of 100 ns, nominal resolution of 50 ps and uncertainty of less than 200 ps rms, and a programmable calibration circuit. The IC also includes several analog energy-summing circuits and thresholding circuits whose outputs are used by the experiment trigger and are live for every bunch crossing. All needed adjustments and optional settings are accomplished using a serial interface and on-chip DACs and registers. Details of the design and results from extensive testing of a set of prototype devices are presented
