## Plot the phase noise of LC-VCO in ADS

Hi; I designed a LC-VCO in ADS and i should plot its phase noise. I persued a clear tutorial so i used HB simulation. I will send the ADS file of output voltage and the parameter which i used in HB simulation to undestand more the matter. After doing all of these steps, i can't plot the phase noise spectrum. What can i do an

## How to build an LM386 audio amplifier

Hi everyone, I just uploaded my tutorial video on how to build a simple LM386 based class AB audio amplifier. If you use the maximum supply voltage it can achieve ~1 watt output. There is also some discussion about mitigating op-amp oscillation which seems to trip up a lot of newbies complaining about noise issues. [video=youtube;4ObzEft2R_g

## ADE GXL Optimisation and Sensitivity Analysis

Hi, Before you choose a tutorial you need to choose in which way you want to improve your circuit. Improvement is relative. One likes to improve his circuit in "cost" and therefore uses a cheaper device. The other likes to improve his curcuit in "noise" and therefore buys a more expensive device. How can a tutorial know this? Klaus

## Books on phase noise

Please recommend some good books on Phase noise analysis in RF circuits. I am a novice on the topic. I was following Rubiola's book on phase noise, but am unable to understand it properly.

## [moved] How to measure noise figure in hspice ?

Hi I need to calculate noise figure in hspice. I read sth in tutorial about .lin analysis(linear network parameter analysis, but don`t know how to use the command? thank you all,

## Low Noise Amplifier Co-simulation with Momentum and Lumped Componentes

New development; I already made the co-simulation model and simulated it with the lumped componentes. Unfortunately, my gain is not what I expected. I get my S11 and S22 like I wanted, but my noise Figure and Gain are terrible apart from want i pretend. I left a figure below with the results. 112423 Any one has any idea what

## simulating phase noise by Hspice RF

dear all I want to simulate phase noise of PLL by Hspice RF. I've read the tutorial, written on it, that the output file must be by using .probe simulation but I can't get it. can any body help me? thanks

## LNA Design Tutorial Series part 3 - Adding Source Inductance

Check out the latest installment of the Low noise Amplifier Design tutorial Series. Adding Source inductance really provided some great results!

## expectation propagation

doing project on "noise adaptive ldpc decoding using particle filtering based belief propagation".instead of belief propagation im going use expectation doubt is whether we can use particle filter in expectation propagation or any other advanced propagation is there to use.else give any idea on that

## flipped voltage follower [hlp]

Hello I want to know more about Flipped Voltage Follower (FVF). I want to know about gain and noise calculations of it. Does anyone know about it? tnx

## PNOISE issue: underestimated kT/C noise

Hi all. I have browsed the forum but i cannot found something similar to my problem. I am following tutorial from K.Kundert on Pnoise simulations of SC. I can clearly follow his steps and the mathematical derivation of kT/C noise spectrum. I am trying to obtain good results from the track&hold example. I use the same configuration of (...)

## Error while simulating for Phase Noise in ADS

Hi, I was following a tutorial on Phase noise from I tried to simulate the attached circuit and got an error message saying " Cannot alter vout. It is a dependent variable" Can you please look into the circuit ( ADS design file is attached in zip folder) and guide me

## How to find the noise figure for VGA?

hi, hw to find noise figure for VGA? pls provide tutorial if any.. thanks in advance

Hi,there I want to simulate the noise performance of my circuit.But I can't find the tutorial in the spectre manual.Anybody knows? My circuit is fully differential op-amp,but in the noise analysis of ADE,I only see single-end input,then how to do? Thanks

## Help me design a NE3210S01 LNA using ADS
