You're correct.

hi I've corrected and uploaded CD4000_v(65a).lib The only corrections made were to the td1,td2,td4 equations used in CD4008B sub circuit. The unbalanced braces/parenths caused syntax error messages in

Oh, I get that by putting a 10cm long unobtanium tube over the headphone cable. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

I have to confess that I was misled by this at an early age, about 13 I think.? The valve doesn't know what the supply voltage is with zero signal. It only knows the voltage between anode and

manauo, Almost all the simulated noise in your circuit comes from the circuit itself.? If there was noise in the sources driving it (V1, V2, V5, V6), it is not present in the simulation.? Those

Any tube sound this design gives you is weird tube sound. Sent: Thursday, February 20, 2025 5:23 PM To: [email protected] Subject: Re: [LTspice] Weird results DC operating point for Tube amplifier

It is missing the symbol for IR2110.? The missing file is ir2110.asy.? Please add it to your .zip file and re-upload it. That is likely to be a cause of shoot-through current. I think it is unlikely

Bruce, Based on your comments, I think I have been able to successfully utilize the SD pin of the IR2110 to eliminate the shoot-through I was seeing. Thanks so much!! -May

Yeah, but then it would not have that "tube sound". Andy ( #DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2 )

No, it is a source follower.? Its voltage gain is unity.? Input applied to gate, output from source pin.? Almost the same output voltage, but shifted 4.2 V lower. The overall circuit has voltage

Yes, an RC high pass filter on the input will increase the noise. Although the capacitor doesn't itself add any noise, it causes the effective input noise voltage to increase, because: Vn(tot) =

You need to find a strategy to enforce some amount of deadtime between the signals. Tuning is not going to do the job unless it is predictable and repeatable, Analog methods tend to be unreliable.

I am having some trouble getting the timing right on my PWM drive signals. What tells me my timing is wrong is the fact that I am seeing what appears to be shoot-through periodically.

At low frequencies, the capacitor's impedance is quite high. the noise current generated by the active stages circulates in this increased impedance, resulting in an increasing voltage.

That is not the subject. The subject is that they try to justify their quirky "design" with objective arguments. Enough said now.

Hello, I don't have much experience using LTSPICE for noise simulations, and I'm having trouble understanding some of the results I'm getting. I'm investigating an amplifier circuit (file "Amplifier

Thanks, Larry. I can't look at it at the moment, but I'll try later. -- This email has been checked for viruses by AVG antivirus software. www.avg.com

John, zip file now has the LMV324.asy and LMV324.cir files. Larry

John, Will update zip file and include the LMV324 symbol and the LMV324.cir.? Should be up there in about 5 minutes. Larry

Andy, Updated zip file so now the symbol in 3Phase_Voltage_Sense_Test.asc is calling 3Phase_Vsense.sub Larry
