Kazizragore Losses in inductor of a boost converter 9. In any case, you need a parallel resistor because of proper DC biasing — unless this block is part of an overall Datasehet loop. What could be the cause of this discrepancy? CMOS Technology file 1. The thing I like to do is look at the spice file for any further clues, the first thing I notice is this:.

Dec The problem, however, is that you already have a large resistor lf36 kthat forces you to pick a value much greater so that at high frequencies the orginal feedback impedance still dominates. Losses in inductor of a boost converter 9. Sign up using Email and Password. Dec Post as a guest Name. You have to make a tradeoff.
It does answer the question and adds some value too, of course imho. CMOS Technology file 1. Equating complex number interms of the other 6. However, from datasheett simulation results, I only got something like 19 dB gain at low frequency and 15 dB at high frequency. Hierarchical block is unconnected 3. Then you can choose a parallel resistor of, for example, k, in parallel with the feedback impedance.
LF Datasheet Following your point on the input offset voltage of 3mV of Datasheeet, I added such amount datashest DC value in my signal source of my original diagram and repeated the simulation. Its offset voltage is listed at uV max on the datasheet they use about 40uV in the LTSpice model and it does not saturate your output in simulation: The thing I like to do is look at the spice file for any further clues, the first thing I notice datasheey this:.
This material is intended for free software support. If I want to build an integrator circuit like this, does this EOS always saturate the output of the circuit?
Hi sixcab, thanks a lot for your very detailed reply and it totally clarifies what I confused about LF May I ask you for what purpose you have a resistor in the feedback path? Part and Inventory Search. Datasheeet — it is somewhat confusing to ask for integrator information although a PI block is needed. Its offset voltage is listed at uV max on the datasheet they use about 40uV in the LTSpice model and it does not saturate your output in simulation:.
Choosing IC with EN signal 2. Distorted Sine output from Transformer 8. I have seen similar issues in the past with LTspice and from my experience it comes down to the dc operating point. And this is finally the ac response for this setup: Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.
The result now looks right now. PV charger battery circuit 4. How reliable is it? If so, how to implement the integrator circuit with op amp having mV EOS in practice? Turn on power triac — proposed circuit analysis 0. Most 10 Related.
