Abstract :
The ILC ECAL front-end chip will integrate many functions of the readout electronics including a DAC dedicated to the calibration. We present a 14 bit DAC, designed in a CMOS 0.35 μm process and based on segmented arrays of switched capacitors controlled by a Dynamic Element Matching (DEM) algorithm. This DAC features an INL lower than 0.5 LSB at 5 MHz, and dissipates less than 7 mW.
