Minutes of the Tracker Electronics Meeting 
Oct 2, 2000

Present: Robert, Hartmut, David, Masa, and Wilko, Dieter


1.	Pickup studies, Wilko:
Wilko stated he would document the testing results. He sees pickup caused by
the Read-event command independent of the shift register clock running. The
other commands cause smaller pickup on the Fast-OR output. Wilko will try to
generate channel hits to see if there is a pick-up problem from the hit
data. Wilko is setting the threshold to 120mV for pickup tests. The nominal
setting is 170mV. Wilko repeated the test of adding a 300uF capacitor on
DVDD to see if the readout pick-up improved. This time it made no
difference. He believes the first test was faulty.

2.	Noise tests - QVDD, Masa:
Masa stated he would measure the effect on noise performance of biasing QVDD
on AVDD2, instead of AVDD (as it is now). He will use a 47pF capacitor on the input.
