There are different sources of non-linearity in a SD-modulator. The assumption, that you mainly see odd harmonics 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
No, you do not any easy alternate. You need to have model for that. Can you share the circuit you want to simulate, may be seeing that people comment on possible sources to introduce harmonic distortion in simulation.
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
i want to calculate total harmonic distortion using fft of supply voltage..plz can you help me out with how to use the fft to calculate magnitude of voltages at harmonic frequencies and then find out the thd.
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. Rgds Raju
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, Ruri
i am not sure but i think when they say HD they mean the harmonic(mul;tiples of fundemental) distortions and when they say IMD they mean non-tones distortion (non-harmonic distortion)
can someone tell how to do simulation in SPICE to calculate harmonic distortions in an opamp.
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.
