How do I calculate the power consumption of an opamp/comparator?
 

For static power consumption, pls sum up current in all current branches. Then get it by I*V. V is supply voltage.
For dynamic consumption, it is better to have simulation and check the current from power supply.
 

Find out the current consumption of the Op-Amp from datasheet of the device, then multiply it with the supply voltage of the device.
 

To clarify, I meaned to measure power consumption in IC design.
If it is system level, please use multi-meter to measure the average current and calculte it with I*V.
For static power consumption, pls sum up current in all current branches. Then get it by I*V. V is supply voltage.
