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.

enter image description here

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?

Thank you!

  • \$\begingroup\$ What is the driver driving? What are the supply voltages? The values of the resistors are given...what makes you think you need to calculate values for them? \$\endgroup\$ – Elliot Alderson Jan 19 at 21:14
  • \$\begingroup\$ Possible duplicate of Power amplifier, does this circuit work? \$\endgroup\$ – Elliot Alderson Jan 19 at 21:18
  • \$\begingroup\$ Vcc = 12V, the resistors are for different voltage values. I just need to know how to calculate Rt_2 & Rt_3 for 2,7V output like on the picture. \$\endgroup\$ – Markus Jan 19 at 21:49
  • \$\begingroup\$ Please provide both supply voltages. Again, what's wrong with the given values of the resistors? \$\endgroup\$ – Elliot Alderson Jan 19 at 22:00
  • \$\begingroup\$ Vee = -12V. I just want to know HOW he got to the values. For understanding. \$\endgroup\$ – Markus Jan 19 at 22:33
