Hello everyone:
I would like to ask one question about the ratio between bias circuit and main circuit.
I design the LNA.
The bias reference current is 100uA, the main circuit current is 10mA.
There are two choice to decide the ratio (1) 1:100 (2) 1:10: ~ 10:100 use two branch
(a) Which one is better considering about mismatch,...?
(b) And except simple current mirror, is there any method or reference talk about high ratio (1:100) current mirror?
Thank you very much
