Hi,

I have read the article on current mirror and understood that current mirror using PMOS can be used as current source and current mirror using NMOS can be used as a current sink.

I am not sure, where can I use current sink current mirror and where current source current mirror in the circuit.

Could you please clarify me this?

Thank you.
 

N-devices are useful when your signal is referenced to 0V ground.
P-devices are useful when your signal is referenced to the positive supply.

P-devices are useful when you want the load (or output) to be referenced to 0V ground.

Sometimes it is convenient to transition from an Nmos to a Pmos (or vice versa) from one stage to the next stage.

The above factors might determine whether you should choose current sinking or sourcing.
