Amplifier Modelling



  1. Voltage amplifier:

For good voltage amplifier Rin should be high and Rout should be zero

  1. Current  amplifier:

​​​​​​​

In current amplifier input resistance should be low and output resistance should be high.  

  1. Transresistance amplifier:

​​​​​​​​​​​​​​

        In transresistance amplifier input resistance and output resistance should be LOW.

  1. Transconductance Amplifier: 

In transresistance amplifier input and output resistance should be high.
