hi friends,
i am designing two stage opamp with bias current 50pA,so to have less current i am increasing lengths of transistor,it is coming to 12m(which is too much),by keeping width 180n.
and my dc gain (45dB) is constant for 100Ghz,i need help ,
give me some ideas to have 50pA current with out too much increase in length??
hoping to get positive replies from all of u
