2. DC operating point 2012-02-24C.Maier2 500mV... 600mV common mode range DC sweep common mode voltage of amplifiers

3. Capacitor parasitic extraction 2012-02-24C.Maier3 Want to put shield under C, to put logic underneath Question: Can we get accurate parasitic C extraction? Answer: Yes, we can. total C C between plates C to metal 3 shield C to substrate total C C between plates C to metal 3 shield C to substrate standard device sim: parasitic extracted:

4. Switch logic 2012-02-24C.Maier4 designed by Kevin Young (draft) We know now that this can be placed under the capacitors
