ericsson: よろしく、お願いします Good day. It's excited here to see someone who is interested in the (sanken) product STR-A6100 series. The Japan's companies seems not good at promotion of

analogspiceman Thank you very much. But how did you get Ae and Ie? The CT (allowing for say 0.5 mm thickness of plastic over the core), has internal diameter 17mm and external diameter of about

Hi, Andy: Yeh, I noticed that 3 minutes ago. Though I hope someone else could explain that later. You are really work-hard man. Thank you Best regards.

"I think the equation in the datasheet "(TI) log112" could possibly be wrong, there is NOT "negative" relation between Vlogout & Vo3." That's because their circuit shows the non-inverting

mmm.... I think the equation in the datasheet "(TI) log112" could possibly be wrong, there is NOT "negative" relation between Vlogout & Vo3. But the simulation shows they are "negative", possibly in

Hi, Andy: Ok, now I see what's the difference, the Vout definition of the datasheet referred to Vlogout NOT Vo3. Vlogout vs. I1/I2 curve is same with the datasheet curve. But Why it can't be shown in

Hi, Andy: Actually, I don't need to consider frequency response this time. I had plot the DC sweep curve, but the slop is negative (Vout decrease while I1/I2 increase). In fact, I used op amp almost

"I don't know what the "uni-polar" means" ?It means one polarity. Andy

Hi, Andy: I had fixed the value (time, amplitude) of DC sweep source (.TRAN) to lower speed, smaller scale. And I found in a very small range, it has exp behavior, but output a DC bias about 4.2V. Is

I re-ran it as a DC sweep, keeping I1 sufficiently positive. I get pretty good agreement with the datasheet's plot, noting the polarity inversion of your circuit, up to about 4 or 5 mA. At that point,

Since it is a log amp, shouldn't the input current (I1, I2) be uni-polar? Andy ?

ericsson.sunshine asked about a Log amp from T.I. This is just a very first impression, and may or may not be meaningful. You are doing this as a transient analysis. It's possible you are sweeping the

Hi, : Here is a pure technical problem. I had found a log amp model (TI) LOG112 at the file folder. When I was trying to plot the "Vo vs I1/I2" curve mentioned in the datasheet, I can't work it out.

Hello, You could use the basic AND, NAND from the folder [Digital] plus a NMOS and PMOS transistor. See the circuit diagram in the datasheet. https://www.idt.com/document/dst/74cbtlv3253-datasheet

Hello one and all. it's time to bite the bullet. Do some digital simulation on an analog simulator :) I need to design a four channel sequential track and hold. Part of this contains a 2 bit digital

Dear Andy, the Standard Ferrite Bead symbol in LTspice of Wurth is not encrypted. Once you selected a particular P/N and right click on the symbol, you can see the datas used for the simulation model.

Indeed, fine LTspice group, I am, most times, happiest to take the advice that one "learns more with mouth closed" ;-) Thanks to all of you who proffer your experience in both LTspice and electronics,
