I need a "driver circuit" for my amplifier. It consists of a dynamic current source, a constant voltage source and a constant current source like shown below:
The constant voltage source should deliver 2,7V. Vcc = 12V
The resistor dimensions shown in the picture are for different voltage values.
1) How can I calculate the current I_v and the resistors Rt_2 and Rt_3?
2) How can I calculate the resistor Rt_5?
