I have a question, please guide me and make me correct regarding MOSFET model selection? Although I used ‘nmos4’ both for 3.3V and 5V Vdd (supply voltage) in my simulation(cadence Virtuoso 6.1.6-64b), in both cases, it works fine and gives same results (according to my observation). So...
I am demodulating a signal. In which Low Pass Filter (LPF) is used to attenuate high frequency modulated signal. The input and outup of LPF is shown. The problem is the edges of LPF output signal is not square [as shown in figure] which result in poorly selection of lower and upper...
I need help in to generate feedback for fan regulator to the controller.
1. AC Fan require 1 phase Ac supply (230VAC/50Hz)
2. Controller require DC voltage in range of 0 to 3V3
3. System is able to support all type regulator, there different type's...
May be it simple question ! but i would need the technical reason Why it happen.
Problem: I am designing signal isolation circuit using capacitive coupling technique using Cadence , CMOS 0.35micro-meter technology . For that i modulate the information signal using frequency modulator on...
Hello i am new on the forum and i want to ask my 1st question.
I have to find the transfer function v(t)/i(t). First of all i calculate the the differential equations and the result is 2+i(t)=ir+c*dv/dt
Then i have to lenearize the e^v and the result is 2*v+1.38.
I think i...
