WebMay 5, 2024 · The collector resistance of the cascode BJT. This gives a pole at 10.6 MHz (with 10 pF), seems to match (although I get -3dB at 5.5 MHz in real world). If I lower that resistance, the gain vanishes, due to the relation with R3. Is there any way to reduce the output impedance? I connected another probe (x10) at the output, in parallel.
