1000 Threads found on edaboard.com: Opamp Power Dissipation
I would need some help in a power dissipation issue.
I have a power opamp that works in a non-inverting topology.
Here some data:
- Single Supply = 12V
- Output voltage = 6+3*sin(wt) V
- Output current = 100*sin(wt + alfa) mA
w = angular frequency
t = time
alfa = angle between current and (...)

Put a zero-volt voltage source in series with all the op-amp stages and then measure the currents through them.
This will give you power per stage - by V*I (of course) and is more useful, than just finding the total power for the opamp.

I am designing an 10 Bit 200 MSPS Pipeline ADC in TSMC 65nm process.
Just finished the design of first stage opamp. It uses the "Folded Cascode Gain Boosted opamp" architecture. The supply voltage is 3.3V. The total current drawn from the supply is around 90mA. Therefore, the first stage opamp itself dissipating around 300mW (3.3 *
