## Forum Analog Circuits Circuit To Measure Current Consumption Of Uc

19/04/2011 · Hi guys, I need to design a **circuit** that measures the power consumption of uP. The uP has to be supplied by a voltage Vcc, and then using the shunt resistor, the **current** drawn by the **uC** is converted to a voltage then followed to the shunt monitor.

28/11/2007 · Consumption is monitored at the input to your **circuit**. **Measure** the **current** from the power supply and **measure** the voltage across the inputs. As he stated it's going to be very dynamic depending on the state (program execution) of your micro. You have to be a bit more specific on the power loss.

24/07/2008 · How would i calculate/predict the power consumption of my **uC** system. There is no LED/LCD display. I would read info. from the **uC** every two months. So, I would like to know the battery capacity required to run it for a couple of months. I would also like to know the general method of finding the way to calculate the power consumed by any **uC** system.

28/11/2009 · Hi Mike! Thanks! This is a third possible **circuit**. I will try your circuitand code next weekend. I know that the nails (also galvanized ones) are not the best sensors for accurate measurement, but i readed other post in this **forum** about a similar topic, and the main problem is that the commercial sensors are pretty expensive compared to other sensors that we could buy in our favorite ...

25/10/2017 · Hi, I am still confused about rms and avg power calculation, which is the right one to use to find the Power consumption in a **circuit**? I want to compare two comparators, one is opamp-based comparator that shows 3uW of rms and avg power values (they are the same here), but for a clocked comparator I got 2uW for the rms power and 50nW for the avg power, so it is huge difference?!

16/07/2010 · Your **uC** max input **current** is 0.2 uA which is not bad but 14K22 for an instance has 0.1 max, typical 5 nA. I mentioned it in relation to having a lot higher impedance divider. I thought you would use that pin as an ADC input and periodically **measure** the voltage. You can monitor the same way the battery - ADC pin.

Set the ideal voltage source value=0 and you can get the whole **current** of the **circuit**. Then, you use the function power=vdd*I(total). This method is not very simple. But I only know this. ... microc **to measure** the total power kw/hour consumption (2) How to ...
