hi all
my question is about the connection of body terminal of NMOS ( i use triple well technology;in which the body terminal of NMOS can be connected to its source)
the defination of source in circuit is the terminal that has the lowest voltage??? Am i correct??
the case in my circuit is as the following, assuming the drain and source of NMOS are connected to nodes A and B
i have two phases ,A is always connected to 3VDD..........in phase -I, B is connected to 5VDD-Vth
and in phase-II; B is connected to 3VDD-Vth
my question is :the bulk of NMOS should be connected to A or B????????the problem is: in phase-I-->VA < VB
but in phase-II--> VB<VA
so what is the soluation????????????????????
thanks in advance
