that V(in) is 5mV, but i need V(in)=50mV, i got a lot of noise on the digital osciloscope for V(in) = 5mV, but for 50mV is acceptable,
i need a Gain around 300. How do i adjust the mode of output transistor? i like self-tuning mode, what post is that circuit ?First, you greatly increase the gain (gain = 1366), and then want to apply 50 mV. 50 mV * 1366 = 68.3 Volts !!!. First, determine which gain you need. I sent you a version with a gain of 290. If you change the supply voltage, then you need to adjust the mode of the output transistor. Once I offered you an amplifier with self-tuning mode. You did not like him. And now you create difficulties for yourself.
