If I have a number of op-amps on a circuit, how do I calculate the power consumption? Do I consider only the quiescent current? Thanks, Eric
Hi Your circuit looks OK , what is your load resistance and load impedance? What is you current power consumption? (V & I in no load) What is your power consumption when applying dc voltage and connecting the input to GND and out put floating ? All the best Bobi
average. The rms value and average value are different. Positive value means the current flow from the power supply and the negative value means the current flow into the power supply. For the negative value ,the power supply acts as a load.the load acts as a source. So the power consumpted by the load should be substracted.
Hey there, I'm having problems calculating the power consumption of a circuit. I got an nonlinear circuit (rectifier) and want to calcutlate the instantanious power. The circuit has 2 inputs, which are conected to an AC voltage source. I can measure the current which flows into the (...)

It is expected to used it for 3hr a day What (...)
I need idea for the ultra low power consumption High Voltage regulator. Input 60V (or even 150V). I want to have linear regulation on the output between 2V and 50V. I have Input between 0V and 3.3V (maybe 5V) and I need proportional output between 2V and 50V. I have found good circuit in Horowitz book (page 369, figure 6.47) (...)
hi how to low power analog circuit? 1. What do you mean how to low power? - If you mean you want your analog circuit to consume less power, here is one of the solutions, try using surface mount devices, the smaller they are the less power they consume, make your layout also (...)
the bigger the cap &res the litte power
I don't think powermill or powertheater will meet your demand because of you wanna estimate at system verification level.
hello all after running a series of analysis in ic5033 on circuit. is there a way to list the power consumption of all devices in the circuit...and maybe do it in an ordered fashion descending or so. many thanks
As we know, MCML draws static power which equal to, P=IV. As far as i know, static here is not mean on leakage and subthreshold. It refers to current source at the tail of the MCML. Let say I want to reduce the power consumption, I can simply change Vdd and current source. Or there is other effective ways/techniques to reduce it ? request
Hi friends when do 10k gates design how much power consumption by CMOS gate with any switch power calculation how do we find static/internal power calculation? thanks Added after 23 minutes: Assuming my CMOS cells are 1.1v and frequency is 500MHz and cell count is 10k.
in some cases there is.. for example.. you can increase the parallelism in the circuit and reduce the clock frequency to get the same throughput. In this case since clock is decreasing with increase in area . so power decreases. But in general lower gatecount means lower power assuming same CLOCK , similar switching activity...
You can calculate the average current drawn from power supply. In the "Output / Setup..." of ADE, you can enter the following express to calculate average current of a voltage source (V1): average(IT("/V1")) where V1 is the name of a voltage source. You may need to calculate average current of VDDA and VDD.
Dear all, May I know how do we normally calculate the power consumption or rather current consumption of a circuit design? Do we sum up the maximum supply current of each component on the circuit to estimate the maximum current consumption? How many percent extra current should we (...)

I am looking an electronic circuit that can approximate the power consumed by an component. The circuit is not used to measure the input or output power level of the component. It is used to measure the component?s DC power consumption by combining measurements of the current through and (...)
Hi all, I have to simulate a circuit for specific inputs. I want to have some results for power consumption depending on input. Matlab environment would help me to manipulate the data very easy. Is it easy to create a power model for a specific circuit in MATLAB? I have some experience in Synopsys (...)

HI Everybody, How do i calculate the power consumed by a single NAND2X gate in a design in a synopsys tool. for eg i have compiled a design in Design compiler and it has 100 gates and it contains 10 instances of NAND2X gate. I want to know the power consumption value of a single NAND2X. How do i report it? Is (...)
Hi What is the best way to measure the duration of the circuit? Let's assume there is no PAE vs power consumption curve plot to see. If people want to evaluate a duration of a circuit, can they only look at PAE without checking power consumption? or they need to look at both? or they (...)
In most cases the input power used in PAE formula is neglected compared to output power (due to high gain of the amplifier). So, never you get high PAE and high power consumption in the same time.
I need help with determining switching speed and power consumption of this circuit. Thanks.52761
That is fine. The power consumption mainly depends on the frequency. If most of power is consumed by delay cell, that should be fine.
Hello, I'm trying to build a power consumption meter using ADE7753. I've designed a circuit (see the picture), made PCB and put it all together. First of all, I tried to run the circuit from external 9 V battery, to see if ADE is ok. It was, so I've programmed driver for it for my ATmega. Then I've wanted to try some (...)
This declaration is about which circuit ? As the Thyristors do not consume power by themselves.

How to calculate total power consumption of a circuit using Cadence virtuoso? pls help, thanks in advance
hello everyone !!! I want know how to estimate the power consumption in sigma delta modulators before the actual circuit level implementation.... can we predict the power consumed by delta sigma modulators while modelling it..
I just want to know that what are the effects of increasing transistor width in CMOS on the power consumption and dealy.
There is an element that measure the current (AC+DC), you can use it to measure any kind of power. This element a general purpose current meter and it may measure DC to all harmonics.
You need to include in which voltage you want to measure the power. Right now you are not specifying anything. Something like this: .meas tran average_power avg p(vdd) from 10ns to 5us
Hello Everyone, Can anyone of you tell me how to calculate or check the power consumption for TCAM (Ternary Content Addressable Memory) circuit in cadence spectre in detail..
The Family of logic parts (Cmos, TTL or other) determines its power consumption when it is sitting doing nothing or is switching slowly. I doubt that a datasheet or a simulation program will tell you the power consumption when it is switching at a high frequency.
it depends on what peripherals are active....You can add Quiscent currents to get Quiscent current consumption.....We need to find Active power consumption, actual power delivered because of switching loads and IC operation....
Hi, folks, I am writing an academic paper about micro-watt 1st order sigma-delta ADC. The schematic is attached here. I need to know what is the ratio between analog components and digital components. I think that that in a mixed-signal circuit, compared to that of analog components, the digital components power consumption is much lower (...)
