Hello,
I have to design a biasing circuit for a Trasconductance amplifier operating in weak inversion region with a 1.25 V supply. I am using Cadence.
I've seen that the Threshold voltage depends slowly (tens of mV) by the dimensions of the transistors.
This causes large variations of the currents even if the aspect ratio is the same.
How can I solve this problem?
Thanks for your reply.
