Hi everyone! I am learning to design a CMOS LNA using Thomas H.Lee's book (The Design of CMOS Radio-Frequency Integrated Circuits). But I am not sure about how to choose the resistors' values of a "Current Reference" (Page 386)??? The values of the two resistors are 1kohm and 2kohm.
The bias current is 5mA in his example. But, if it is changed to 6mA or another value, then how to correspondingly change the values of the resistors of the "Current Reference".
I read some books about current mirror and current reference. But the Current Reference used in Thomas H.Lee's example seems not a general structure explained in these books. Looking foward to your answer. Thanks!
