The steps and procedure for 2nd order LPF design

[alpeshchokshi]

Can any one send me the steps and procedure for filter design,
more specific 2nd order LPF... the designing should be at transistor level...

please send me any reference or papers..

Thanks,
Alpesh

Re: Filter Design

have a look at this paper and you would get idea.

Filter Design

firstly, you should know which type filter that you want to use according to your spec, active-rc, gm-c or switch capacitor.
then use some software such as matlab or filter solution to get system level filter ciruit
finally, use trasnistor, capacitor, resitor to realize the block of the filter, such as OTA, gm-cell and opamp.

Filter Design

You can have an opamp level filter designer at
microchip.com .. they have a filter design cad tool
called "filtercad " just check that .. you will get an
idea about the design ...

Re: Filter Design

actually im looking for butterworth higher order filter or biquid circuit through which i can realize all the filter

Re: Filter Design

i need a systolic architecture design for a FIR filter
i am a matlab code for a FIR filter with 8kz cutoff freq and ripple in stop band and pass band is 0.01, the transition bandwidth is 300hz.
i need to produce the filter coeff . can anyone help me
