Hi All,
I designed Beta Multiplier for pbias = 0.8 V and nbias = 0.4V at 1.0 V supply for 90nm. While I get right values for the biases in dc analysis, in transient anlaysis it gives different values. Could it be that startup circuit is not working properly as the Vbiasp = 0.2V and Vbiasn = 0.9 V in transient analysis ? If so, how should I go about fixing it ? Also, I tried only multiplier circuit without any start up circuit. Again I face the same problem. Or is it that pbias = 0.8 V and nbias = 0.4V are not possible at 1.0 V ?
I will appreciate any help in this regard.
Regards, Kanu
