I work as an analog-mixed signal/rf engineer for Aura semiconductors. I have MS in analog design and a published author in IEEE.

## Re: Fractional rate asynchronous conversion for highly oversampled data

Hi Slartibartfast and All,Thanks for helping me out.This is the below scheme which I am thinking will just do the picking of samples. I am just worried about the...

## Re: Fractional rate asynchronous conversion for highly oversampled data

Hi  Slartibartfast,Can you explain a bit on how does the max jitter of 2*pi/1000 is estimated?Thanks

## Re: Fractional rate asynchronous conversion for highly oversampled data

Hi All,To clarify the specific question about the input and outputs. The input sampling rate is ~10 kHz, and the input content is within ~10 Hz. The data needs to...

## Fractional rate asynchronous conversion for highly oversampled data

Hi All,The general method used for fractional rate conversion is to use a polynomial based filtering of the input data like a Farrow structure. This structures are...

## Re: anti aliasing filter

You need to look at integrated noise after the filter which is given by (m0)*(equivalent noise bandwidth of filter). For example: if you use a first order filter,...

## Re: Bit width in a digital delta sigma

Hi ShahramThe Digital DSM is part of a two point injection modulator. The topology of the DSM was finalized from system level simulations in Matlab. But it is an...

## Bit width in a digital delta sigma

Hi,In the attached DSM MOD-2_DSM, how does one determine the bit-widths? Is there analytical relation of bitwidth in relation to the input bitwidth? How does one...

## Re: Multi-loop, Multi-input Multi-output(MIMO) loop stability

Hi Tim,Thanks for your reply. So if all loops are stable then the complete closed loop is stable. I am also of the same opinion. But I think this is a sufficient...

## Re: Multi-loop, Multi-input Multi-output(MIMO) loop stability

Hi JOS,Thanks for your reply. Is there a criteria how large the eigenvalues can be for a particular performance? What I mean is, for continuous time single loop...

## Multi-loop, Multi-input Multi-output(MIMO) loop stability

Hi,In classical feedback control, ie single loop controls, the stability is well studied and analyzed using Nyquist plot or Bode plot. One can tune the open loop...
