Hi everyone,
I need some help plotting the following equation in AWR :
|G|=S21/(1-S11*S22)
I tried to use the output equation box but we can only specify whether it is a magnitude or phase. I tried this but the output is not correct
Anybody who can help or knows a tutorial on plotting...
yes.. I have read the tutorials. I am using Microwave Office. I am not designing the amplifier. I am using a commercial amplifier, MAR 6+ with a MEMS resonator. I have made the phase shift =0 and gain > 1 at resonant frequency for open loop simulation. But I did not put the input impedance of...
Hi Abshikebabs!
Thank you for your help & explanations. As you suggested I am learning how to use series feedback. I would like to use the topology shown below.
I am also reading how to perform the open loop simulation based on Alechno's paper which can be found at

Hi all,
Can someone help me calculate the increase in resistance of a conductor due to the skin effect?
The skin depth of a conductor is given as d=sqrt(1/pi*f*u*sigma)
where sigma=conductivity, u=permeability, f = frequency
Once we have obtained the skin depth, how can we calculate the...
Thank you both. But the article Compensating for Ideality Factor and Series Resistance Differences between Thermal Sense Diodes.. how is it related to -ve resistance? perhaps you can explain to me a bit?
Thank you abshikebabs! So are resonator can be both feedback and have -ve resistance. It is...
Hi all,
I read somewhere that oscillators can be classified either as a feedback or a -ve resistance. What is the difference between the two?
Thanks,
Anis
Hi all,
I am new in the design of oscillator and was hoping someone can help me.
Which method should I use for designing an oscillator using MEMS resonator?
i) Linear Simulation using OSCTEST
ii) Negative resistance simulation
Thank you
Anis
oscaprobe simulation
Hi all,
I am designing an oscillator using a MEMS resonator and the minicircuits MAR6 amplifier. I have done the simulations based on the steps shown in the link below:
I performed the open loop gain simulation and plotted the S21 transmission characteristics. I added a...
Re: LVS
3.You didn't define a pin named INP in the layout. Check the layout again and make sure you didn't wrongly spell INP or defined the pin in the wrong metal layer.
2.You probably didn't connect all the grounds together in the layout. Make sure that all the grounds of different subcells...
If you are using standard CMOS process, you can also use all metal layers and connect them with vias. This makes the probe pads thicker and less susceptible to have all its metal scraped off when probing.
You can also make the pad bigger so that it will be easier for you to probe it when using...
