Gain Bandwidth Product (GBW) of Op Amps
zhlédnutí 8KPřed rokem
Guess what the Gain Bandwidth Product is? Not surprisingly, it is the product of the frequency and the gain at that frequency on a Bode plot of an op amp. This video goes into detail about this important op amp characteristic.

Intro to Stability for Op Amps
zhlédnutí 4,8KPřed rokem
Using negative feedback with op amps brings all sorts of advantages - a controlled gain, controlled impedance, improved bandwidth. But it's not all kittens and rainbows. Instability is the dark side of op amp negative feedback and this video outlines what stability is and how to check for stability in a circuit To see more about operational amplifier check out: www.electronx.ca/education/op-amp...
Op Amp Open Loop vs Closed Loop Gain Response
zhlédnutí 16KPřed rokem
The open loop gain of an op amp is very big, but the bandwidth is quite small. When you create a closed loop circuit, you give up some of that gain but get more bandwidth. This video goes into detail about why this is the case.

Non-Ideal Op Amps: Input Bias Current
zhlédnutí 4,1KPřed rokem
Input bias current is an unavoidable feature of op amps that arises because the input impedance of op amps is actually not infinite and there is some current that must flow into the inputs when the op amps are operating. This video describes why input bias arises, the effects that it has on the circuit, and ways to mitigate the effects of input bias currents. Input Offset Voltage Video: czcams....
Non-Ideal Op Amps: Input Offset Voltage
zhlédnutí 4,3KPřed rokem
Input offset voltage is one of the non-ideal characteristics of an op amp. It can be modeled as a small voltage source in series with one of the input terminals of the op amp. Input offset voltage is an unavoidable property because it is due to the semiconductor manufacturing process. It can be compensated for either through modifications to the external circuit or by adding compensation inside...
A Brief Explanation of Negative Feedback
zhlédnutí 785Před rokem
Negative feedback enables the output of a system to be maintained at a certain level or value. It does this by taking some measurement of the output, comparing it to what is expected and then adjusting some element of the input or system to keep the output within its acceptable range. This video describes negative feedback in a little bit more detail using block diagrams and examples to help wi...
Op Amp Integrator and Differentiators - Alternative Analysis
zhlédnutí 1,5KPřed rokem
In this video, I use an alternative approach to deriving the relationship between Vin and Vout for both an integrator op amp circuit and a differentiator op amp circuit. This alternative approach involves analysing the circuit in the frequency domain and then using an inverse laplace transform to bring the equation back into the time domain. Don't worry though, the transforms are really easy an...
Differentiator Op Amp Circuit
zhlédnutí 6KPřed 2 lety
Once again, the name of the circuit is the thing that it does. So this circuit differentiates, or takes the derivative of the input voltage to create the output voltage. Well, it doesn't actually sit there and do the calculation, but the output voltage is proportional to the derivative of the input voltage and in this video, I show you why. To see other common operational amplifier configuratio...
Integrator Op Amp Circuit
zhlédnutí 16KPřed 2 lety
The integrator circuit does exactly what you would think that it does...it takes the input voltage and integrates it to give the output voltage. Yes, circuits can do calculus. This video derives the equation for the relationship between input and output voltage of an integrator circuit, provides some examples of where you might find such a circuit, and goes through a few simulation examples. To...
Difference Amplifier Using an Op Amp
zhlédnutí 14KPřed 2 lety
A difference amplifier is one that outputs a signal proportional to the difference between two input signals. This video shows how to calculate the amplification that the signals get based on the external resistors. This video also shows some simple simulation examples using LTSpice To see other common operational amplifier configurations check out: www.electronx.ca/education/op-amps/common-con...
Summing Amplifiers
zhlédnutí 3,9KPřed 2 lety
A summing amplifier is one that takes in more than one input and sums them all together to give the resulting output. The amplifier might also add a gain to the voltage. In an audio system, this would be called a mixer because it mixes the signals (different audio sources) together to give one resulting signal. This video describes two configurations, one that is inverting (the inputs are phase...

    I have a simple question, and it may depend on its application. But what if we supply(Vin) to the negative(-) input instead while the positive(+) terminal is tied to Vout. I believe this configuration is also Vout = Vin ? It's more common to supply the positive input... why is it ?

  • @nicobriceno732
    @nicobriceno732 Před měsícem

    Awesome video. I would note that you can get an easier and quicker answer to solving the circuit by doing KVL in each loop and solving for currents 1 and 2, Since these elements are assumed to be behave linearly. By getting currents 1 and 2, you can solve the corresponding voltages across the resistors. I solved it this way and i got the same answers. Knowing this, i am just confused as to what came first and how to connect these ideas. Does KVL incorporate superposition through the currents ? OR is it better to think about these ideas separately?

    FYI “watch your p’s and q’s “ comes from the days of typesetting. In those days you set the mirror image of text you were setting using separate little metal characters. It was easy to confuse or flip a letter upside down. So the p, q, d and b always required extra attention as they were all easily mistaken. (Crap I’m old!)

    For those saying the values are wrong at the circa 6 minute mark, the end value of 43.232mA is actually correct. However the error lies with the resistance value used to divide by. On the example the combined impedance of ZL1, ZC2 in parallel with ZR1 was used (449.11 Ohmz < -17.147) when the value of resistance for just the ZL1 and ZC2 should have been used (1523.3 Ohmz < -90) which then gives approximately 43.232mA. Hope this helps.
