Hello all,
I am now designing a clock driver for a folding **interpolation** **adc**. The output of the clock driver is connect to 32 comparators. The clock signal needs to be generated is 2GHz. Does anyone have experience with designing such a high speed clock driver??
Thanks for your help,

Bandpass sampling is best approach to have reduced power consumptation for the **adc** implementation.
I think most **adc** implementation independend from the architecture (Flash, Folding, **interpolation**, Multistage-Subranging,..) come down to about 150-500fJ/decisionstep.
So a 10bit/1GS/s have
(2^10-1)*1e9Hz*150fJ=153.5mW
These results (...)

Hi Everyone,
I have just designed a 8-bit folding **interpolation** **adc**. When I simulate my **adc**, I cannot get to 8-bit of resolution. The SNR that I got from the power spectrum is only -30dB.

You are experiencing some "numerical noise" due to the **interpolation** between two simulation steps, i.e. your 2048 points do not always fall on one of the points calculated by the simulator. So, the 0.01ns simulation is probably the correct one.

why use folding **adc** architecture ??
flash **adc** -> < 6bit and much more power
flash + **interpolation** -> 8 bit
pipeline **adc** --> can reach high bit high speed
I think many design use pipeline **adc** for Scaler
(as I know is 165M 10bit pipeline **adc** ..)

Hi Circuit_seller
I have not used AIC23 chip.
I just brawsed the datasheet for you and in my opinion the normalized frquency should be interpred like this.
The '3' should not be interpred as a pi
The **interpolation** filter in the **adc** works at the frequency much higer then the input sampling rate (44.1khz for example).

let me sum up some basic rules:
- more pixel (higher resolution) you have, smaller are the pixels or bigger is the sensor...
and
- smaller are the pixel size, worst is the image ( smaller light to current/voltage conversion ratio : SNR !)
- bigger is the sensor, more expensive is the system (smaller yield, large lenses...)
so, basically, t

F/I **adc** work exactly like a flash. You have comparators and a resisitive string. You comparators have couple of stages of low gain preamps. One preamp/comparator generates one zero crossing (zx) at the referece value, because you look at Vin-Vref.
Now imagine you can actally compbine severeal preamps and generate more zx in one "folding amplifier

The change in voltage should be proportional to the change in temperature
Because the divider output voltage is proportional to the ratio Rx/(Rx + R0), it's not linear in Rx respectively temperature. In addition the non-linear Pt characteristic has to be considered, as you mentioned. Nevertheless, using a simple ratiometric RTD "sig

Not sure about specifically what kind of resampling topic you are looking at.
Resample can refer to aligning signals that need to be syncronized. For example if you have two independent async digitized audio signal that need to be combined into a single data stream you need to resample one or both to get symbol/bit alignment to allow combining
