hi:all,
now i want to restruct one paper used in 5th ctsdm with single opamp Resonator structure
he has show the STF&NTF
69229
so i can struct matlab simulink like
69230
because it used Resonator
so for the stability
we need to put the zero before pole right?
but the NTF is 1/(1+H)
the r

hi , i will simulate a differential opamp with pins vin+, vin- , Vcm , Vout+ , Vout - . i 've already done it ,the link below show this , but i dont know how simulate Vcm between the Vin+ and Vin - ,???
my desired model is A , but i could only upto B

Hi,
I am going to build the simulink models of a Pipeline ADC, including SHA, each stage of pipeline ADC,clock generation, digital correction. The non-ideal of switched-capacitor opamp should be included. Eventually I can get the plots of INL, DNL, SFDR, SNDR, and ENOB in the Matlab. Is there any examples I can follow? Or where to get more informa

Hi, I'm a licenciate student in Finland. I am looking for Analog/Mixed-Signal/RF IC Design Job in Europe or US.
I have about five years IC design experiences. I designed DAC, LPF, PA, opamp. I'm familiar with most popular EDA tools like composer, virtuoso, hspice, hsim, spectra, spiceexplorer, calibre, xcalibre, protel, matlab/simulink etc. I ha

Hi,
I want to know how we can model the opamp's gain and BW in a discrete-time (switched-cap) integrator in simulink.
Any suggestions?

Dear all:
I am now desinging a 2nd-order sigma delta modulator.
The architecture is gain=0.5 in both Integrator. ( Boser / Wooley 1988)
I use simulink to run simulation. (SDT Tool
by S. Brigati Ver.(0.1) 08/04/98)
Input: 0.5 sinewave
Quantizer: +1 / -1
opamp saturation voltage in Integrator: +1.35 / -1.35

sdtoolbox is very good in extracting opamp characteristics and other ckt nonidealities e.g. noise and applying them to simulink

I have simulated a 3rd order CT sigma delta ADC in simulink...now I want to build it in cadence using spectre.. 0.3u technology
The main blocks are:
1)Integrator for which I will be using an RC-active opamp integrator
Now how should I go about its specs??The gain,bandwidth etc
2)Quantizer...I have no idea abt this...any quantizer

In spice you can model one block of your circuit with current-controlled and voltage-controlled sources and define it as a subcircuit. for example you can model an opamp with two resistors for input and output and a voltage-controlled current source. at a higher level simulink is very good. like modeling of a whole delta-sigma modulator.

Hi
Let me know how to do implementation half delay (z^(-1/2)) in Matlab simulink for switch opamp implementation.I can onlydo implementation delays greater than 1.
Pls give me an advise.
Thanks

hi,all
i am a beginer in analog ic design and recently in my first project sigma-delta ADC.
my case is: 1 bit, cascade 2-1-1modulator, 64 OSR, in simulink SNR could be 108dB, considering KTC noise/clock jitter/nonideal opamp,SNR could be 97dB, noise level is about -140dB.
then i begin my circuit.
when simulate circuit, it is s

hi guys,
probably this is naive..
how to use the simulink with this model.. i have no idea...
thanks
