i know that there are ways to convert passive resistor to active resistor using transistor.can anyone teach me the simplest way in converting it?i've tried using pmos or nmos but couldn't get the desired voltage drop and current value.
i need to draw a layout of a couple of passive capacitors.can anyone teach me how to draw it?my capacitors value is about 100pF to 500pF.i have another option to draw using parasitic capacitance but i don't know how to calculate w/l.is there any notes or tutorial that i can refer to?fyi,it's...
thank God,finally i got the right lpf response.im lucky to found you here.really appreciate it.thanks mists.
the circuit that you gave me is a multiple feedback lpf,right?i don't even know that it is one of the sallen-key lpf. :)
i need to design a 2nd order analog low pass filter using active lpf.my filter specs are:
fc=400kHz
using butterworth response
i've simulated the lpf circuit but can't get the right lpf graph(bode plot).fyi,i've calculated all the resistors and capacitors according to the given formula but end...
0.18um cmos two stage opamp
i need an opamp to use in my 2nd-order low-pass filter.the specs are:
*fc=400kHz
*use butterworth response
what are the best specifications for an opamp to use in that lpf?
i had designed a two-stage opamp but i don't know wether it is right or wrong.also,i don't...
can anyone explain to me the steps or stages to design a low-pass filter for vlsi design?i really dont have any idea.as far as im concerned,calculation is not suitable for layout design.then,how do i determine the resistors and capacitors value?what is the different between the practical filter...
transistor active low pass circuit
really?hmm,it seems that i need to find other alternatives to overcome this problem.anyway,thanks to all.i really appreciate it.
low pass filter with transistor
hmm,it seems that all the circuit that you show me are all consists of resistors and capacitors.does anybody know how to convert the resistor and capacitor into transistor?is it possible to do so?
filter transistor
thank you IanP,windmillkity and js.i'll try search in the website you gave me.:D
actually,i need to design a butterworth low pass filter.what i need is a circuit consist of transistors only.if i were to design a layout based on RC circuit,then it might be large and not...
transistor filter
i have a project that is to design a schematic diagram for low pass filter in transistor level.the reason that i need the schematic diagram in transistor level is to design the layout.the question is,is there any schematic diagram of low pass filter (any type of low pass...
