You could vatasheet the model yourself and make it better if its worth your time. What I want is the high gain as much as possible at low f and datahseet constant gain at relative high f. All of this makes me wonder if there is anything wrong with the spice model of LF downloaded from the TI website which seems not likely or if there is something about this JFET input op amp I didn’t understand not suitable to use for integrator circuit.

Choosing IC with EN signal 2. I tried a few values, and the highest I could go was 40Meg just on the brink of saturation: This material is intended for free software support.


ModelSim – How to force a struct type written in SystemVerilog? Hi sixcab, thanks a lot for your very detailed reply and it totally clarifies what I confused about LF It does answer the question and adds some value too, of course imho.

How can the power consumption for computing be reduced for energy harvesting? At dc, the gain would be about 11 and the offset will produce an output of about 33mV. But you want high gain at dc—not good with the offset. The poles for the second and output stage are probably wrong.

AF modulator in Transmitter what is the A?

LF356 JFET Op Amp IC

Look at the location of the ac source now:. Look at the location of the ac source now: Its offset voltage is listed at uV max on the datashheet they use about 40uV in the LTSpice model and it does not saturate your output in simulation:.


The ‘N’ just means it has a DIL package. They call it EOS in the model file. Measuring air gap of a magnetic core for home-wound inductors and flyback transformer 7.

You could downsize the value of Rf to, say, 20k. I used the LTpsice to simulate the feedback performance of a integrator circuit with op amp LF which is a JFET input op amp but I go strange results see the image below. So choose an opamp with better offset specs is an option. Input port and input output port declaration in top module 2. How do you get an MCU design to market quickly? Yes – it is somewhat confusing to ask for integrator information although a PI block is needed.

How reliable is it? Equating complex number interms of the other 6. The time now is Maybe the datasheet has the wrong plot, or the wrong schematic for that test, or maybe the model is wrong.

And this is finally the ac response for this setup: Dec 248: What could be the cause of this discrepancy? Losses in inductor of a boost converter 9.

The other type would be LFBN. Synthesized tuning, Part 2:
