Dear friends
I am designing CMOS adaptive biasing operational amplifier, this technique is providing a dynamic bias current that increase as the input increase, the circuit that I designed is providing this increment attentionally so at a little high input the bias current is going to be very large and more than what I need.
The solution is that I should have like a current limiter circuit at the bias terminal that would allow the accepted value to pass and limit the maximum value for what ever the input value and I need your suggestions for this circuit.
Thank you all
Regards
