Hi all,
I need to model MEMS devices, in particular accelerometers, using Simulink. I also have access to MEMS Pro and Coventor. Does anybody know how I can either extract the pre-made sample models from Coventor or MEMS Pro into Simulink, or where to find models for Simulink.
I have also...
Hi All,
I am working on this project where I need to simulate the following circuits:
> Figure 4.4 shows an xor gate. I need to know how it works and the different parameters I would need for its functioning (which are Iss, Vb I1 and R1)
> Figure 4.5 shows a current-steering differential...
Re: 8-bit adder
How do you measure the worst case delay?
I think it is when you add 11111111 + 100000001 = 1 10000000
The simulations definitely seem to confirm that... but I might be mistaken.
Again, we are using the Kogge-Stone 8-bit adder (too late to change it now). Oh yeah, there is no...
Hi All,
We have a project to implement an 8-bit carry lookahead adder in cmosp18 technology. Do you have any suggestions on what type of logic to use? At the moment, we are thinking of implementing a logarithmic adder (Kogge-Stone) in static CMOS, but one thing that we noticed is that we have...
lamp neutral wire
Hi All,
My friend bought a neon lamp in Japan. It has 2 wires coming out of it: a black one, and a black one with white stripes. The voltage rating is 190V.
Now, he wants to use it in France, where they have 220V of supply. So, he wants to connect it in series with a...
export von waveforms cadence
Never mind, I worked it out:
You click on the "table" view on the calculator, then specify the range, and then print it....

Now I am really confused for the ICMR. Is it where all the transistors are in saturation, or where it can track the input DC voltage?
sndr calculation tutorial in cadence
Hi All,
I am building a delta-sigma ADC in Cadence, and need to measure its SNDR. For that, I want to import the waveform and then manipulate it in Matlab. According to the course's tutorial, there is a "printvs" function in the calculator. I just can't...
the problem is in the CM input and output ranges
My specs are:
- DC gain > 60 dB (maybe a typo... I am assuming this means the AC gain.. maybe he meant DM gain)
- unity gain bandwith > 170 MHz
- slew rate > 150 V / us
- settling time within 20ns (withing 0.4% of the final value)
- input and...
DC voltages:
However, in the specification, it says that the input CM should be 0.9V. Now, if I introduce the offset voltage at the input to make the output voltage 0.9V, won't that violate the specification? Some people have been telling me to do this.
Added after 13 minutes:
The ac and...
The W/L of all transistors when the DC sweep was done was very large (500-1000), so I don't think that was the problem. Theoretically, if W/L is large, that would mean that Vov is small for the same current, and therefore the voltage swings would be high... not low... No idea what's wrong.
Hi All,
We are doing this project at school, and we are going crazy.
Does anyone have any experience with the following circuit:
**broken link removed**
Our biggest problem is our input and output common mode range, as you can see here:

Now, this CM DC sweep was...
