<promach> I have a mosfet question. For https://en.wikipedia.org/wiki/Winner-take-all_(computing)#/media/File:Wta_2input.png , why I(in,1) increases, then I(out,1) increases ? they are not npn bjt transistors
<promach> but this is within a SINGLE mosfet
<Bike> it says t hey're biased subthreshold, so they're kind of like bjt active, yeah?
<Bike> the paper goes through it in detail (thank god, i'm terrible at this)
<Bike> yeah. p5 and 6 basically
<Bike> um... the losing output transistor is shut off, so, the winning output transistor has to have Ibias - Iin1 through it, so its gate (winning input's drain) voltage increases
<promach> Bike: may i know why " its gate (winning input's drain) voltage increases" ?
<Bike> not minus. none of the input flows through the bias source. dur
<Bike> um, because there's current forced through it by the bias source, i guess.
<Bike> the gate-source voltage is a function of the log of the current, and the source voltage is more or less fixed.
<promach> Bike: I got to go. I will have to continue the reading later
