Hello
I am designing an OTA with improved linearity and I have used source degeneration technique and the source degeneration is a MOS resistor operating in triode region. I dont know how to adaptively bias the gate voltage of the triode MOS(source degenerated). The OTA is operated in sub-threshold region except the source degenerated MOS. Can anyone help me in adaptively bias the gate of the source degenerated MOS.
If I fix the gate voltage of triode MOS then the source and drain voltage will vary due to which the linearity will vary thats why I have to use adaptive biasing
Thanx
