Dear friends,
this is one of the most popular ampliifer circuit which I am in love with it
I have a question about adding cascoding transistors down to MP5, MP6 and up to MN3, MN4 for the purpose of boosting the gain. This procedure I have seen with OTA same type circuit but without the class AB driver stage, so I am not sure about the consequence of doing it with this circuit.
In general, adding cascoding transistors consuming from supply headrom, however, since we have here two stage ampliifer the signal doesnt require to fully swing in the range since the driver stage provide us with gain as well
I am looking forward for your reply
Best Regards
