    Designing a Differential Oscilloscope Preamplifier

    so does that mean that if I've got a dc offset of 2V i should have a ratio of 2:1 on the resistors? which resistor should be higher Rcb or Rbe? from the output of the cascode does it run through a cap or not, and to where of the Vbe multiplier? I am having trouble with the output stage as...

    im designing a preamplifier, but my waveform is sweeping at around 2.5 volts, as the is a preamplifier it should be swinging around 0.0 volts. Does anyone know would to fix this problem? i am only using discrete components no ic's as this is one of the specs. the specs are as follows: 1...
