The recommended injection resistor value that can be used is between 10-Ohms to 50-Ohms.
The purpose of the injection resistor is to provide a 'break' in the feedback network of the control loop where the injection signal can be inserted for performing a Bode Analysis. Since we do not want to interfere with the DC bias setting of the feedback network, we use small values of injection resistors.
