1. JC and Marina 04/02/01 Pixel Cross Talk Study  Modeling: Linear coupling between neighbor rows  Parameters in the simulation:  FPIX0-Pstop gain curve  noise: 105 e, external ADC noise: 400 e  threshold 2500 e, dispersion of threshold 290 e  The number of pixel per cluster increases for small angle  The resolution actually improved with 5~10% cross talk  More realistic model needed ( Information from Abdel, and ISE-TCAD and PSPICE simulation)

3. Jianchun (JC) WangSyracuse University3 Effect of Signal Coupling  A simple linear coupling between neighbor rows  Smearing effect of linear coupling can be taken away with  correction  Small coupling (5-10%) improves the resolution

4. April 2, 2001 Future Work Simulation of the signal formation in Si (ISE-TCAD) Simulation of a capacitor grid attached to Front end electronics (PSPICE) New input Parameters For simulation We need some model of the front end electronics to implement this plan
