    Problem with generation of triangular wave

    Hi! I am working with comparator (In LTspice). I have to compare a sine wave and a triangular wave. The triangular wave should be at 2kHz frequency. So this should be the configuration for triangular wave: However, the results show that it is not a 2kHz frequency:- Last time I checked...

    DeltaT circuit using 10K thermistors to output 2-10vdc control voltage

    I need some help with a simple circuit - I want to convert the difference between 2 resistors (actually 10K thermistors) into a linear 2-10 vdc voltage output. If the resistances are the same, the output voltage is low, the greater the difference the higher the output voltage up to 10vdc. I am...
