current consumption of OTA

[r@m$]

hii...

I need to find out the current consumption of an OTA...

but i dont know what is it actually.... what doe sit mean??

and how can i find??

 

[leo_o2]

Probe supply current with simulation. However, it depends on loading condition.

thanx for the reply leo_o2

but i didnt understand what u said....

here is the OTA cirucit for which I need to find the current consumption..
can u help me..??

In simulation, you need to add a voltage source between vdd and vss. And probe the current of the voltage source and obtain the current consumption.

tanx for the reply... And do u think it doesnt vary with the input voltage??

 

[leo_o2]

If good bias is employed, the current consumption will vary little as input voltage changes.
