    Hi all,
    i'd like to create a zener diode with Vthr = 420 mV, Is = 4uA
    and I(zener) = Is*(exp(V(zener)/Vth)-1)... i can't figure out how to do anything like this. I created a custom current soure that I thought obeyed these properties but it seems to output current constantly so that can't be right. Any thoughts on how to approach this?
