hi all,
I am wondering how to bias a nmos/any device with constant current source. I tried connecting drain of mos to the current source and the other end of current source is connected to Vdd.(=1.8V), but when i try dc analysis with varying Vg, the drain voltage varies from 70V-0V, which i hope is not correct. can some one suggest me what is wrong with the method i followed, or any other effective way for current bias. (I am doing a very basic circuit, i hoped the circuit will function without trying current mirror and all).
thanks!!
