Re: Mechanical switch
Hello David, You could make a bouncing switch with a V-source (PWL) as the control voltage for a switch SW. You can see a "typical" bouncing switch on the top-left picture.

Re: Need help to design a transimpedance amplifier
You have an impossible set of criteria for a linear TIA. You ask for 100mV per 100nA. 100uA is 1000 times larger than 100na. So, your spec would have 1000 times 100mV out with 100uA in, or 100V. You

Re: Input impedance of an energy saving fluorescent lamp (CFL) 21W
CFL's are very non-linear, in fact exhibit negative resistance. There are a few Spice models on the internet, you may have to adapt them for LTspice. --- L'absence de virus dans ce courrier

Re: LTspice IV (NOT RESPONDING)
It's because your computer is being slowed down. Maybe you need to run a tune-up application. Just emptying some files, like Temp and Recycle Bin might help. Defrag the hard drive, too, if you can
