Hi all,
I am designing an opamp in a low supply voltage process (vdd=1V). in order to get a feeling of the circuit I have designed a simple diff-pair with a tail current source. the main problem I am facing now is acheiving a good mirror to the current source as the Vds of the mirroring device and the current source are different and limmited due to the low headroom of the diff-pair. can anyone suggest a biasing network for low voltage current mirrors? of recommend a book discussing this topic?
Thanks
