Abstract :
The proposal of a vertex detector for the International Linear Collider (ILC) using DEPleted Field Effect Transistor (DEPFET) detectors [A DEPFET based vertex detector for the detector at TESLA LC-Note, LC-DET-2002-004, DESY, April 2002] states challenging requirements for the readout-electronics and the sensor itself. In contrast to hybrid pixel technologies, DEPFET sensors integrate a first amplification stage in the detector. As the signal readout is non-destructive, the DEPFET requires a reset (clear) mechanism. Optimization of the clear mechanism addressing radiation hardness and timing are presented. Furthermore, the minimal duration for a clear process resulting in a readout free of reset noise will be shown to satisfy the timing requirements of the DEPFET-ILC readout scheme.
