So it seems this is a job for LNA?
What is the difference between LNA and opamp? Arent they both supposed to amplify?
Would you help me in referring to similar researches and papers/books on this?
I wonder if this is a project assignment? If so, how much ignorance is required to release it to a student? I suggest to rephrase it: "Show, why it's not feasible to design..."I need to design an opamp that takes a 1 Ghz AC input and amplify it with gain larger than 70 dB.
I don't think, that the term needs further explanation. You can calculate, that with 70 dB gain a few pH common ground inductance for in- and output will be sufficient to fulfill the oscillation condition.What do you mean it will oscillate? Ofcourse this is on a single chip..
I understand, that you are asking how to achieve the required total gain for a sensitive receiver?But how am I supposed to understand my received signal if its amplitude is a few hundreds of micro volts only with an LNA of 20 db gain?
