Bias network for amplifer

[tender_006]

Hai all,

i want to design some active and passive bias network for my amplifer. But dont know how to select the DC block capacitors and inductors. if someone have any artticle plz share.

waiting for ur replies!
regards,
tender

That is a good starting point

As a rule of thumb I will like also to add
Your DC blocks I assume are the coupling capacitors, well at the frequency of your operation chose a capacitor that its Impedance Zc=1/jωC is really small (1ohm for example ), however make sure that u operate below the self resonance of the capacitor. Same goes for the inductor, You want the inductor at your bias network to present a high impedance at any AC current, that means you need a high inductance value, how ever you need again to operate below self resonance.

Also Check AVX and ATC websites , they give some more information about Coupling,decoupling and DC blocks use for Capacitors.
