Don't you think you can bowl down both modes with Iself<10? ? An LDO's output power will be determined by the W/L size of the output device; the remainder of the circuit shouldn't change its power (current) consumption distinguishably dependent on power (current) output (provided that it's a full MOS (...)
any one please give me the pspice code of any 1bit 14t full adder along with the circuit.inpt output charecteristics,power dissipation,power consumption,time delay,and any other charecteristics are required as output for different technologies and different temperatures.please try to include power grating (...)
You can put some back-up capacitors to increase the circuit working time out of external energy source. With the battery, supply a low power comparator (its current consumption actually depends of your need) with a battery supplied reference, say 3V, being the compared voltage one generated by the external power supply. (...)
In case of doubt, a solid ground plane won't be bad. The LED driver circuit can't work. The IR-LEDs have only 1.2V forward voltage each, so a simple series resistor from 5V would be the appropriate way to supply it, or a buck converter if minimal power consumption is a must.
can I use a LM1117 LDO regulator to provide 3.3V If you read its datasheet you can get your is no because LM1117 LDO comes with 800ma output. And other thing you are just designing the supply according only sim900 also consider the other device power consumption I think you need at least 3.3v and more then 2amp l
No! Remember Ohm's Law? If your circuit draws just 1 milliamp, it will drop 10 volts across your huge resistor. You have a volt meter, but you don't have an ammeter? Forgetting that for a moment the big question is, what do you mean you "want to give exact power"??? Will you adjust the voltage so that you supply some fixed power? Or adjust (...)
Without knowing any of your parameters process size bulk or epi process type of circuit power consumption of circuit guard ring spacing guard ring width ... I'd advice: max. contact spacing < 5*contact_size .
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

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 (...)

I think that tutorial is out of date. Have a look in the help at saif_map. For a tutorial, look at the power Compiler user guide.
i am looking for a tool that will take the netlist generated for the verilog description and give the power consumption details I presume this task should be strongly related to the manufacturer library, furthermore am not sure if you can down into component level during simulation. What are exactly the technologies y
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....
If we talk about digital IC, the power consumption is classified as: STATIC power DYNAMIC power But if we refer to any analog IC related papers, only single power is mention for any relevant circuit like 0.25mW, 4mW, 0.6mW (milli Watt), etc..Can anybody explain why is it so?
The circuit power consumption is the power drawn form the supply source minus the delivered output power (if any).
Each device has either its resistance (resistors) or if it is an active device, you find its current rating in specifications. Your circuit is a load for its power supply. You must use or make a power supply that can deliver the required current to the circuit while the DC voltage would not drop. Current in electronic (...)

Hello, I want to measure the power consumption of charge pump (its a double dickson charge pump built using switch cap circuits). Can anyone suggest how to measure the power in any state? When I try to measure the current going through the supply, there are spikes that settle down within the clk period. Do I have to (...)
This is my humble opinion as an embedded system engineer (not analog designer). I would go for the Zener because less components are used so the implementation is simpler hence a more reliable, smaller and cheaper circuit. Also the power range does not justify an octocoupler.
Hi, My problem is that the power consumption behavior of my circuit is highly dependent on the data values (current and previous) therefore I want to produce a random input to my circuit, the randomization here is in the timing between each consecutive pulses, I mean that the time between each two pulses is random while (...)
There are lots of ways in doing that. (You didn't mentioned the voltage, so I assume its a low voltage circuit with very less power consumption.) Search in google for square wave oscillator..
u have to measure current consuption and for practical consumption use dc power supply it will show u corrent consumption and then calculate using P=VI formula.
To measure milli-amps, you typically put a resistor inline, and measure the voltage across it. Its value should be low enough so that it does not reduce supply V to the circuit you are testing, yet high enough to allow a sensible reading on your meter (DC or AC or oscilloscope). A suitable value is 2 to 5 percent of the circuit's impedance. If

If "switched off" means tri-stated, you can expect a rise of buffer current consumption when the input voltage floats to intermediate values. It's the same with any CMOS buffer. A hold circuit can be used to prevent input floating, at the expense of slightly increased dynamic power dissipation.
Hi, I am trying to implement a gps tracker circuit that will be powered up by a li-ion battery. Thus, I need to estimate my average power consumption.

Hi How to calculate the dynamic, static and leakage power of given logic function. (Example given in image) Post added at 23:32 ---------- Previous post was at 23:31 ---------- Is there any free tool to calculate power.
Your circuit will not work with AC. The circuit will work as long as you provide enough base current and the collector current is not higher than the specified max current for the transistor. The power consumption of the transistor and temperature should be within limits too. A mosfet doesn't need the "base" current for (...)
