Hello,
I am attempting to design a LNA with a BJT. Why would I use a collector bias resistor instead of a large collector inductor or LC parallel resonant circuit?
The only advantages I can think of are:
Resistor:
1. Gain over a larger bandwidth
2. Impedance matching would be easier over a broader range of frequencies.
Inductor or parallel LC circuit
1.Would allow me to design with a smaller supply voltage.
Has anyone else got any ideas. Thankyou
