Default LME49830 Circlotron

Hello,

I would like try to sim and amplifier with LME49830 Amplificateur Circlotron Lateral mosFet & LME49830

For the moment I have made a "simple" schematic like the datasheet but there is no quiescent current on MOSFETs

This is the first time I use tina.

Could you check my file?

Thanks
Best regards
Sébastien

I have play but it is not so nice as LTspice, how to probe things? I can sim and have output but when choose probe there I can see nothing extra when use that probe for voltages.

Hi kees52,

I have made the circlotron schematic, with IRF for the moment, I do not know how to add lateral MOSFET

Do you want the lateral mosfet or the vertical? I have to read paper about the lme what is possible, I did see there also bipolair.

You need to find a lateral model for tina.

In the meamtine I have find out Tina, here I need meters to get the output, but I do no yet now how to probe there, is this only possible with these meters I can add?.

I do not know Tina at all, so I do not know how to do an analysis

for the moment lateral or vertical does not matter, the LME is made for both MOSFET

Later today you get anwser, I see you have differnetial supply for the chip, and floating supplys on output because of circlotron the ground reference resistors are quite high, need to drive the gates properly can be issue also normally you have two halves also the chip, how to do that properly as the chip is not made for circlotrons. I am a litte curieus now maybe because you use just the single output, and does this not danger the chip.

I get the hang for Tina already, just play with as it is your woman.

regards

Yes 100ohm for groung res is enough

I have doen the sim.


It does work so at hand, but I doe not now why there is no voltage over the Vbe multiplier, maybe beause of model or the open P output.

it does with 1 volts in give 30 volts out, try in multisim.

VM3 is the meter over the vbe transistor, as you see no voltage and you see the crossover clearly om VM1 wich voltage is symmetric from zero volts.

regards

It looks like Vbe fuction is not in model, it does nothing also with the schematic in examples.

But it does work, I think just build one channel and see.

What concern Tina. the wireing and placing components is not mine favorite, program is difficult and LTspďce is a lot better with probing and so.

regards
