How can I design a transistor amplifier that gives -1 amplification?
I want to generate a + and - input for briged amplifier configuration.
and I notice the distortion is very critical, I tried a common emiter configuration with Rc=Re=4.6k, and with biasing at the base for NPN 2n3903, it simulates fine in SPICE, but in real application, the output from Collection is always smaller. I really don't understand the logic since the IC should be very close to IE.
thanks
