vccs in cadence
Hello at all,
sorry the troubele but I have a problem, i want replace the input trasconductor stage in mixer gilbert cell with two ideal elemnts vccs. I want that this vccs has a gm of 16mS. I attached two schematic, the first is the circuit with input trasconductor with NMOS, the second circuit is with vccs. In the second stage there is some problem but i don't know witch. To define a gm in vccs of 16mS, i set the parameter trasconductance equal to 16m but i don't know if is the same thing.
Thaere is other important parameter that i have to set??
Thank you very much
