I think you misunderstand what I mean, I dont wanna change my current source's circuit, I hope I can change the output signal of the source which is flat and constant to a square wave.
I have a CMOS accurate constant current source (1mA), now I wanna it be a square wave, maybe 50% duty is fine, what kind of CMOS circuit I can use to change it ?
Thanks for your reply, my question doesnot match with these documents, I mean, my main frequency is very low, 50Hz, and these documents are good for the high Frequency AC input. I know this, and I just want to know, did anyone do the low frequency 50Hz 220V AC plannar Tranformer?
I want to design a 220V 50Hz AC to 5V AC current is around 5mA~10mA PCB planner Transformer.
The efficiency is just more than 10%, that is enough.
Here is the question ?
1 Can I design it? Did anyone design this? Because the winding N is around 45:1. I think it will be not easy, but my...
I am a chip designer. I have some questions about power converter.
Now I want to use a simple device to convert the 220Vac to a low DC (1~3V current is around 10mA). The efficiency demand is not very high, more than 10% is OK. I want to design this power supply to a chip.
First idea is to...
thanks, i know your mean, but i asked why it has to be like that, for example, why the sin signal frequency has to be the tone_bin/Nfft. and for NBW, why NBW=1.5/Nfft
%% Simulate the DSM in time
Nfft = 2^13;
tone_bin = 31; what is tone_bin?
t = 0:Nfft-1;
u = 1*(nLev-1)*sin(2*pi*tone_bin/Nfft*t); why the input signal has to be this, what this means
v = simulateDSM(u,Ha,nLev);
figure()
n=1:1000;
plot(t(n), u(n), 'g');
hold...
