You're smarter then.That is the best you have? Pitiful. The pet rock i never got would be embarrassed to meet you. Does any of the following applications have on buttons: word processors programmers editors compilers schematic capture tools other cad tools spreadsheets video editors audio editors databases mathematica/matrixx/mathcad/octave/maple/macsyma all the various programming languages please answer carefully. ?-))

I am using ngspice-23 on a Fedora 14 machine running GCC 4.5.1 Please note that the circuit is still experimental, and so not optimized or efficient. *M0 2 3 4 4 M_PMOS L=1.2u W=1.5u *M1 4 7 0 0 M_NMOS L=1.2u W=4.5u *M2 2 6 5 5 M_PMOS L=1.2u W=1.5u *M3 5 8 0 0 M_NMOS L=1.2u W=4.5u Hello Daku, Your Mosfets are too weak. They only have Idmax=2mA. The ratio W/L for Power-Mosfet is more like 10000 to 100000. This means W should be many m (milli) instead of u. Example: M1 4 7 0 0 M_NMOS L=1.2u W=50m Best regards, Helmut

The provider (linear technology) is biased towards their own parts. One advantage is the ASCII netlists produced by this GUI application are easily posted on usenet. And thus easily run and understood. In addition to wine you need to also install "xchm" if you want to use the online help. -- ⚂⚃ 100% natural --- Posted via news://freenews.netfront.net/ - Complaints to news@netfront.net ---
