Hi Guys,
Currently im designing an opamp for my design familiriaty. If you noticed from my schematic there are 2 PMOS biasing. For bias1, i believe what i have done is correct that is I biasing them according to W/L ratio. But as for bias2, i believe that biasing shouldn't be like that as the VGS is not same at the two points. Actually i need a biasing bias1=1.1V and bias2=1.0V. So, i meeting some problem here on designing the current mirror biasing for the 2 pmos. Please guide me how do I overcome the issue.
Thanks,
Anachip
