sorry~~can i know how to get the correct noise value for my designed filter?? my designed filter get the cut-off frequency at 1.4354 MHz..
is it the noise value need to get at cut-off frequency??
Here i attached the input noise and output noise result~~
i use the noise analysis~~i know that at Direct Plot Form there can choose Noise Figure Function, but my input source is not a port, so can't be executed...Then i just execute output noise function and input noise function..and get input noise= 9.758mV/sqrt Hz and output noise= 156.2pV/sqrt Hz
Thanks to reply..Then input noise= 9.758mV/sqrt Hz and output noise= 156.2pV/sqrt Hz, the bandwidth (cutoff freq)= 1.4354MHz, can make those noise values into dB?
Thanks to reply~~~i' m not really don't understand what you said~~is it V/sqrt Hz cant be convert into noise figure in dB..
Because actually i m doing filter and carried out noise simulation using cadence..then i get input noise= 9.758mV/sqrt Hz and output noise= 156.2pV/sqrt Hz..But my...
Dear all,
Could anyone teach me how to convert noise value in V/sqrt Hz into dB?
For example, if i have input noise= 9.758mV/sqrt Hz and output noise= 156.2pV/sqrt Hz, the bandwidth (cutoff freq)= 1.4354MHz, Then how i can convert the noise value into noise figure in dB?
The attachment shows the layout of a part of my designed circuit..the purple is the layout of capacitor (fm3m1) and left one is NMOS transistor...How i can connect the capacitor with the poly (gate of NMOS)?? because i don't know what is metal inside the capacitor fm3m1 (purple)..
thanks for teaching me~~
But my target is about 40 dB for noise figure...it is a large different with the measured value about 144.42 dB (shown in attachment). How can i fix it and get my target value??
Besides that, i also have another question is about layout. If i want to connect capacitor...
hmm~~~
What is your mean main form panel to choose the unit..?? Now i have do the noise analysis based on the link u given: https://eda.engineering.wustl.edu/wiki/index.php/How_to_Perform_a_Noise_Simulation_in_Cadence...
i get the result is like the attachment below..how i can know how much the...
Thanks a lot for your reply and giving me the information...
1. But i don't understand abt the value in noise summary, what is the unit for the noise contribution?
2. If i want to get the waveform by having noise figure in dB, how can i do? is it possible i change the input voltage source to...
Hi everyone,
Could anybody teach me how to get the noise figure and power consumption of OTA-C filter by using cadence 0.13um technology?? what analysis in cadence i can use and how to use the analysis??
Thanks~~~
Hi everyone,
Could anybody teach me how to get the noise figure and power consumption of OTA-C filter for cadence 0.13um technology?? what analysis in cadence i can use and how to use the analysis??
Thanks~~~
Hello,
1. Could anyone help that how to determine noise figure and power consumption using cadence software for 013 technology??
2. How to draw the layout of capacitor in cadence??what is the name of instance of capacitor??
Thanks~~~
