There are different sources of non-linearity in a SD-modulator. The assumption, that you mainly see odd **harmonic**s is of course based on prerequisites, generally speaking no even terms present in the polynomials describing the transfer characteristics of individual building blocks.
There's a paragraph about **distortion** in the **simulation** (...)

Before you start to test linearization algorithms (I assume, it's a kind of adaptive pre-**distortion**) in Simulink, you should verify your mixer models. I'm not familiar with the RF toolbox. Basically non-linear diode characteristics and **harmonic** analysis (e.g. by FFT) should work for your purposes.
Apart from your special intention to test C-code

Hello,
I need to simulate the **harmonic** distorsion of two OpAmps (ADA 4817 and AD 8033 and maybe other similar) at different frequency (range Dc to 20Mhz).
I am lucky to have access to Orcad Pspice. Unfortunately the models provided by Analog Devices tell " **distortion** is not characterized ".
Any suggestion or workaround ? Thank You.
The only

hello friends
So far I was enquirer how to simulate or calculate the SNR.
Now I would like to ask you how to simulate the THDN (total **harmonic** **distortion** plus noise) of the operational amplifier.
Thank you and I appreciate very much your answers

Hi everybody, I'm having a little troubling simulating the **harmonic** **distortion** for a MOSFET differential amplifier with ADS. I am trying to calculate HD2, HD3, and the point at which the apparent gain drops by 1dB all for a 50mV signal at 100 MHz. I set up the circuit and added the **harmonic** Balance **simulation** block and set (...)

hi
presently i am worlking with Mentor graphic ELDO Spice for analog circuit **simulation**.for measuring specification of my amplifier i have to measure **harmonic** **distortion**(HD). i dn't know how to measure HD of a wave form by using EZ wave calculator of the mentor graphics .please guide me.

I want to optimize a model in ads using the measured nonlinear **distortion** data. In HB **simulation** environment, I can not find ways to write the measured distrotion data such as **harmonic** **distortion** and intermodulation distoriton into the goal function. Could anyone give me some guidance to solve this problem?
Thanks in advance!

Dear All, thank you for reading this topic. I just design an OTA and I will conect it to a capacitor to build a lowpass filter. Then I will put a 100mV sine signal at the input and want to see the **harmonic** **distortion** at the output. Does anyone show me the procedure that how can I get the result? A sample is put in the attchment and t

Hi, guys,
How to simulate the total **harmonic** **distortion** (THD) in Cadence Spectre simulator?
Many thanks,

i am not sure but i think when they say HD they mean the **harmonic**(mul;tiples of fundemental) **distortion**s and when they say IMD they mean non-tones **distortion** (non-**harmonic** **distortion**)

hello all,
i have designed a 10 bit ADC and i would like to simulate the major ADC characteristics.....but my knowledge in **simulation** of ADC characteristics is quite limited.......the characteristics i want to measure are the following:
1-DNL
2-INL
3-input offset voltage
4-Total **harmonic** **distortion**
5-Spurious Free Dynamic Range (...)

My question is how to extract the nonlinearity of a Gm-C integrator, i.e. THD (total **harmonic** **distortion**). SNR (Signal-to-Noise Ratio) and SDR (Signal-to-**distortion** ratio)?
As my knowledge, these perforamnces are from the FFT of a signal. Does it need a tranisent **simulation**???
In some literatures, the performances 1dB (...)

in my opinion,
if u only are only careing about the switch's linearity, u can build a ideal switch and then compare the result of S/H with ideal swtich to the S/H with real switch.
i think u will do FFT for the output of S/H to see any **harmonic** through the S/H network.
