Making the converter in transimpedance amplifier topology is possible, but involves a 100 mA capable amplifier circuit and respective high current consumption from the power supply. A shunt plus voltage amplifier topology is more appropriate for current ranges above 10 or 20 mA.
Cost and performance are the main criteria. Performance includes, efficiency, regulation, power consumption and speed of circuit design requirements vs supply voltage. However in logic ALV technology offers both speed and low impedance at lower voltages than older technology CMOS by virtue of smaller lithography.
Any idea how to convert voltage to current linearly without using opamp or just using simple circuit? For example, Vin=1V, the output current will be 100uA. Vin=2V, the output current will be 200uA. Do not use power-consumption circuit, such as opamp. Thanks.
What about a simple relay that when the power drops away will switch through the battery?
I used single pHEMT transistor to design my LNA, and set Vds = 3 V,and Ids = 60 mA. I have got the power consumption as Pdc = Vds * Ids = 3 V * 60 mA = 180 mW. I used the single supply voltage as Vdd = 3 Volts. I used the same three pHEMT transistors for design of my LNA. I set the each transistors biasing as Vds = 2 V, and Ids = 15 mA. When I m
hai all How much power will be consumed by a MOS mixer(typical circuit) circuit and ring oscillator- from the reported works? Is there any methods for reducing the same?
For the full adder circuit realized with one 3-input XOR gate for sum, three 2-input AND gate and one 3-input OR gate the power consumed for these gates is x mW. The full adder circuit designed from two 2:1 multiplexers, one XOR/XNOR, one AND/OR gate based on the value of c input is ymW. I find that y>x. I request you to let me know if this (...)
Hi I need to design LDO which will work also for retention mode where SPEC for self current is very low. For regular mode Iself <800u For low power mode Iself<10u Somebody have an expirience for such kind of design? Lets say i can design high power amplifier and switch it for low power mode - but during the switching LDO output (...)

Hi, I am recently assigned to a project which is highly related to power management. The problem is simply like this: There is a circuit that already works but it is wanted to work on some areas constantly have power line down issues. So, I need to design a power management circuit that will always work with (...)
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

I created schematic of my logic in Quartus II. i want to check the power consumption in this circuit for various boolean gates by converting them to CMOS technology. i request you to let me know the software/procedure to obtain this. i tried to use Pspice but the format of the file it accepts is different.
You are reporting PIC16F628A absolute maximum ratings as power consumption. I presume, you didn't understand the meaning of this datasheet paragraph. Actual power consumption must be calculated according to the DC Characteristics section.
Hello everyone, I am doing my project using Tanner EDA in S-Edit for low power double-tail comparator. I have obtained the average power after simulation of the circuit.

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?
Hello all, I have a circuit made of mosfets in pspice using the netlists, now i want to calculate the power consumed by the circuit. How do I do this, please help me in this regard. any leads would be of great help. Thank You
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..

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.
