For larger load resistances, the output-current error does increase significantly—from about 50 nA to 800 nA. However, 800 nA is still a very small error. How much do you think the load regulation will change if we replace the ideal op-amp with a macromodel intended to approximate the ...

There's lots of course pdf's on op-amp circuits, ideal ones and non-ideal. Some good video's on youtube too. Today I should make a proper test-jig for some op-amp DC-parameters, I just want to fit a few test circuits on a proto-board, some are easier/quicker than others. ...
When designing a circuit in LTspice, you may wish to assess the impact of component tolerances. For example, the gain error introduced by non-ideal resistors in an op amp circuit. This article illustrates a method that reduces the number of simulations needed, and as a result spe...
Resistors are modeled as ideal thermal noise sources. Real resistors can have additional noise called “excess noise”. Op-amp noise modeling in the 1/ƒ region may not be accurate. Undocumented Bonus Tip LTspice allows the noise in a resistor to be ignored in the analysis. For example, ...
Hi, the circuit misses on: - a gnd node as reference for LTspice ... LTSpice doesn´t like floating circuits - misses on a load (connected to gnd) - misses on a resistor from the OPAmps In+ to gnd as a dc-input-bias-path ...
op-amps to operate like ideal voltage sources. This ensures maximum power is delivered at the output giving your ADC the best values. The closer the output impedance is to zero the better. Similarly we want the input impedance to be high as to not draw current from the source. Let's ...
TheLT8714is a synchronous PWM DC-to-DC controller designed for a 4-quadrant output converter. The output voltage cleanly transitions through zero volts with sourcing and sinking output current capability. The LT8714 is ideal for regulating to positive, negative, or zero-volt outputs when co...
The file you posted is a “symbol” that uses the default ideal model…correct? I know this really doesn’t mean anything to anybody else but, I created a “Spideys_Models” folder placed the symbol file in there and then registered the path in Control Panel, and now I can see the sy...
