8.20 Using the topology of Fig. 8.4, design a single- input, single-output BJT amplifier with a gain of -150. Choose values for Vcc, VEE, Ic, and Rc. Can you suggest a simple modification to the circuit that will yield a positive gain of +150?

BJT (Bipolar Junction Transistor)
A BJT is a semiconductor device with 3 terminals that consist of a p-n junction diode that can amplify the signal or current. It is a current-controlled device. The three BJT terminals are base, collector, and emitter. The BJT works with the charge carrier, the two type of carriers in the BJT are holes and electrons, the charge carriers flow by the process of recombination. The signal to be amplifier is generally given as the input at the base terminal and an amplified form of it is available at the collector terminal.
I am having trouble with a Differential Amplifier problem that I attached a photo of. I must "Design a single-input, single-output BJT amplifier with a gain of -150. (Based on figure 8.4). Choose values for V sub CC, V sub EE, I sub C and R sub C. Also suggest a simple modification to the circuit that will yield a positive +150 gain." Please provide clear explanation of the logic behind the steps of your solution so I can have a comprehensive understanding.
