1 CARIOCA - prototype 8  One chip for next submission : September 13 th 2002  Modification on positive and negative versions  Bipolar version  With analog buffer for probing positive negative positive bipolar prototype 8

2 Bipolar version Bipolar Channel prototype 8 positive negative positive bipolar positive negative bipolar switch negative positive

3 Bipolar version  Positive amplifier  Negative amplifier 1 st and 2 nd stages are identical

4 Bipolar version  Positive amplifier  Negative amplifier Feedback and last stage can be switched off…

5 Bipolar version  Positive amplifier  Negative amplifier Acting on gate bias and using basic inverter switchgate bias bias

6 Bipolar version Bipolar version it is much worst w.r.t. note LHCb-2002-40  Bipolar amplifier negative positive switch

7 Bipolar version  Bipolar channel bipolar switch = 0 or 2.5 V negative positive Positive signal Negative signal

8 Bipolar version  Analog pads for probing
