Pole and zeroes in alalog design

[pvreddy]

Can anybody explain how we can determine poles and zeros by looking at the circuit.

Or suggest any material on this topic.

In generally, pole is derived from the output stage of AMP, power output.

 

[pvreddy]

But my qs is how we can know how many poles and /or zeroes exist at any node.

Hi,
You simply determine tne function of transfert and wich is:
Vout/Vint
= H (s)

G(s)
= ______
Q(s)


Zeros are the values of s for which G(s)=0
Poles are the values of s for which Q(s)=0

Dear pvreddy,

an old (1970) and excellent book by Gray and Searle ("Electronic Principles") explains how the poles and zeroes of a circuit can be found "by inspection", i.e. without need to set and solve the equations.
Probably the volumes 3 and 5 of the SEEC series by the same authors contain also the stuff.
Best regards
