looks like this is long time ago.
I don't think you have a loop in this circuit, unless you have a feedback voltage to control you are pumping or not, then you have a loop, for that loop stb, stable means less ripple on the output, unstable means more ripple on the output, you can calculate the...
I don't know whether I am right to ask here, but I just have no idea where to ask.
recently I am looking for the implementation of a dual port sram (cmos, ~2kB ~30MHz low leakage), is there any paper or website that I can turn to, and I am a totally beginner at this area.
Thank you.
Re: harmonics reject mixer
Thanks vfone!
The problem is the LO I used is ideal LO, and the performance is monotony with the frequency, and the peak value is shown at 1~2MHz, for frequency lower than 1MHz, the HR ratio goes down again, I think is it because the new induced phase error by the...
harmonic reject mixer
I am working on harmonics reject mixer, down-convertion, working from 150kHz to 30MHz, using 6 of 8 LOs(pi/4 from each other, we use 0, 45°, 90°, 180°, 225°, and 270° LO) and us 0.7 as the ratio close to 1/√2 (0.707) with 1% error,
I used pss+pxf simulation, when the LO...
poly resistor 1/f noise
Thanks Soben,
I saw their expression for flick noise of a resistor is
Vn²=Vbias²×0.5×10e9/(WLf)
which Vbias is the voltage difference across the resistor, W and L is the dimension parameter of the resistor, is that right?
resistor low frequency noise
Do polysilicon resistor have flicker noise?
How to characterize the flicker noise of polysilicon resistor?
are there any papers or books I can turn to?
Thanks
recently i am working on a complex band-pass filter, and encounter some problems, anyone can help me
as the fig posted, when the center frequency of the filter is designed lower than 500kHz, every thing seems normal, the outputs increase linearly as the inputs increase. but when the center...
I am working on a complex filter for wireless communication, 6-stage, biquards structure, for ideal inputs, the outputs is good enough. the image suppression (-2M Hz) is 70dB, but when mismatch occurs in the inputs (0.3dB in magnitude and 1° in phase), the image suppression have reduced to...
