    How to gather low voltage analog signal

    if you want a ready-made solution you can use data acquisition card and associated software. Matlab also support data acquisition card. https://www.ni.com/data-acquisition/ https://eie.ucr.ac.cr/uploads/file/software/pdf_matlab/daq/daqug.pdf

    Interrupts in Soft Uart

    you can write your soft uart code inside an interrupt sub-routine.

    Interrupts in Soft Uart

    you have to consider the interrupt pin for this. external interrupt

    change input condition after checking the output voltage in Hspice

    I tried but same result i as got before. anyway thanks a lot. i think should consider verilog for this.

    Interface GSM and GPS both with 8051 using Tx & Rx

    i faced same situation and i used 2-1 mux in that case you also need a controller pin to control.

    change input condition after checking the output voltage in Hspice

    I think the if condition cant resolve the output value only the parameter you defined it is one alternative of .alter command. i got error "unresolved condition in .if" for .if((time>1e-6))

    Need help with 7-segment displays

    try this. in that case you need five pins and a for loop

    Need help with 7-segment displays

    USE 1-4 Demux. and you need to write a loop which switches the demux within 0.1s to make system unnoticeable of being blackout any character.

    change input condition after checking the output voltage in Hspice

    Actually suppose my simulation time is 1us. at 0.5us if the output is greater than vdd/2 i want to change the input condition, may be frequency or amplitude of the input signal.

    Need help in selecting Topic for research

    visit https://ieeexplore.ieee.org/Xplore/dynhome.jsp and search for recent works first. then you can get some direction.

    i need help in my first designs using Cadence

    1V or 3V is for vdd for this mosfet. you can refer to cadence manual.

    pcb drawing problems. Urgent !

    **broken link removed** you can study this video tutorial moreover while exporting your design there is a scale option . if you put scale =1 that mean actual size.
