    Concept of Bootstrapping in Electronics

    Dear Team, I was trying to study about bootstrapping in electronic circuits. When I checked in Internet Wiki says it is a method to improve the input impedance of an amplifier. In the power electronics context, it has another...

    MOSFET's model selection for different voltage source (Vdd).

    Hello, 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...

    Obtainig Low Pass Filter's output signal as square edge.

    Hello 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...

    Modulating frequency of Multi-vibrator circuit (CMOS technology)

    Hello, I am modulating control signal with Multivibrator circuit in CMOS technology. I use this formula (1/2.2RC) to find the frequency of modulated signal with multivibrator. But my simulation (result) and theoritical (calculation) of frequency is not matching. I am using CADENCE software tool...

    Voltage level shifting of Signal After passing through capacitive isolation.

    Hello, 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...

    Adapting an old CRT Viewfinder ( 9.3 V DC / 2.7W )

    Quarantine project: Adapting a Sony BFV-20W viewfinder Scroll down to skip the background info As a cinematographer, I've always really felt most comfortable shooting with a viewfinder. However modern electronic viewfinders all exist in the "prohibitively expensive" class of filmmaking...
