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

RE; Yes, what? You asked, 'Or can they?', and the answer is, 'Yes, easily'. Well, of course Bravo wouldn't give figures that showed less than excellent performance. The THD with 33 ohm load is

ALL the .ASCs report 'Can't find model LMV324', and there is no symbol in the schematic, just a blank space. The readme.txt file doesn't mention the LMV324. I've just now downloaded the ZIP and

Maybe there is. The OP is probably on a wild goose chase.

Yes what? I don't care, but Bravo Audio seems to care about figures that are long accepted as performance indicators.

John, Do you need to include LMV324 symbol and model, isn't that taken care of when you generate the net list?? As mentioned in the readme.txt file the 3Phase_Voltage_Sense_Circuit.asc has the LMV324

Already did that and the outputs still are not correct

Andy, The 3Phase_Voltage_Sense_Circuit.asc was the original schematic that simulates properly. Modified that schematic to create 3Phase_Voltage_Sense_Model.asc, which I used to create the netlist and

Hello Connect a ground to neutral in ....test.asc

No more difficult than 1m of coax and 2 gold-plated phono plugs. People still buy them because they hear something on that Alice Cooper LP they didn't hear before. It's probably tinnitus, but don't

There really isn't any point in criticizing the design. It's deliberately weird. An LM386 makes a good headphone amplifier, but it might be difficult to sell for $130.

Yes, it's a circuit that works, somehow. However there are many more efficient and stable ways to bias a MOSFET and to provide voltage to a 6V heater from a 24V source. BTW, source-follower it is not.

Yes, easily. Consider, for example, these two amplifiers: a) Output power 30 W, THD 0.1% b) Output power 35 W, THD 5.2% Which would you buy? They are the same amplifier. Similar games are played with

BTW, I did another run of .TRAN 10m (without UIC or Startup) this time flagging the checkboxes "Noopiter" and "Skip Gmin stepping" under Tools->Control Panel->SPICE (basically it amounts to add the
