It is well known that it is difficult to filter the noise generated by switching power supplies, and this difficulty increases as the PSU is supposed to deliver large currents. For example, in a us...
While the terminology is similar to that of microcontrollers, and of CPUs in general, the "register" term here is specific to energy meters. Essentially, this board is a very basic version of a sma...
They aren't specific to the project, but to the MCU. As long as you use the same MCU for multiple projects, they will be code compatible. Some hardware peripherals are even code compatible between ...
I'm curious about FPGAs and would eventually like to get into them sometime during the future, so I'd like to ask three broad questions to help orient myself: In what applications are FPGAs the m...
First, that's an archaic chip that requires a lot of circuitry around it to do anything useful. Why use this particular chip? Second, the datasheet gives you an example of how to use this part as ...
Moderator Note If this site were mature, this question would be closed because it solicits opinions, or is too specific about particular models. In the interest of site activity, answers are being...
I have a MAX809 with RESET pin connected to the gate of IRLML6344. I will rephrase my question. At 5 V, RESET is also 5 V and the LED lights up. But if I add the fan, RESET drops to 0 V and draws 1...
Before we get into your problem, there are a few things to say about your descriptions. You need to step back and think about what we know and don't know, then learn to communicate specifications ...
The charger is supposed to output 20V-24V when the roomba is plugged in. However it's only showing 1.6V. If this is really true, then there is no point going further. The charger isn't working, t...
Setup We can best understand the behavior of the tunnel diode in the region with negative resistance if we imagine it as a self-variable (dynamic) resistor R driven by a variable voltage source V ...
Imagine a battery pack with <=60VDC of maximum voltage and a load of up to 10kW of power(the PMSM inverter with the input capacitance of up to 1mF). The load is not always known - could be 100uF...
Your question really comes down to how a delta-sigma A/D works. The A/D internally models the input voltage with a stream of bits. Each bit can only indicate the minimum or maximum voltage. The ...
A differential amplifier amplifies the difference between the two input voltages but suppresses any voltage common to the two inputs. Based on this scheme the differential amplifier is substrac...
Both differential amplifier and differentiator react to a voltage difference. But in the differential amplifier, the difference is between two voltages applied to the amp inputs at the same time wh...
I need to know what is the difference between differential amplifier and differentiator A differential amplifier amplifies the difference voltage between two signal voltages. A differentiator ...
I fully agree with OP considerations about measuring the transistor output curve. We can very easily and precisely set successive current values with constant increment. Thus, the IV curves will be...
Figuratively speaking, Olin Lathrop's answer is a wonderful story about the unequal "tug of war" between a "pulling up" resistor and "pulling down" switch. And, when the switch is 'off', the "strug...
First, draw schematics properly when you ask others to look at them. Your right to left flow is rather annoying. There are two main possibilities for this circuit to cause noise, the inductor and ...
No need to power the led with 5V. 3.3 V should suffice! Before I come to problem of regulating the current with only 3.3V, I wish to state some general simple constructions. Technically speaking,...
I have tried to drive a series of smd led with constant current. If it is rated for 3.3V, I run it at around 3V. It doesnt get hot even without a heatsink, ~60C. So thermal runaway is only a proble...
In my 15 yrs of intense deadline R&D for new state-of-the-art design in my 45yrs experience, estimation of time is inversely proportional to the number of mini failures from bad assumptions fro...
Although the voltage drop across the current-sensing resistor R6 is floating and it can "move" between the 28 V rails, the A1A op-amp input voltages can (have to) vary within the 5 V power supply. ...
Microwave Materials, Spectrum then EMI effects on SNR of WiFi, BT. There are a lot of measurable parameters in microwave dielectrics which affect; Dielectric Constant , Dk between conductors an...
Baud rate is about the speed of bit slots in the channel or symbols. Bit rate is the rate at which actual data is transmitted. Put another way, baud rate is what you see when you look at a scope ...
Our on-topic page currently lists homework questions as mostly off-topic, in the following manner: No interest in understanding or learning, "Just gimme da anser!" There has to be some element ...
