Please give your answer in two decimal places. Vcc 9 VEE VRE VER

In the above circuit, BJT's VT values ​​are not identical. a) For the collector currents of transistors to be 2 mA What should the R0 value be? b) Find the values ​​for gm1 and gm2. c) Find the differential mode gain (ADM). d) Find the common mode gain (ACM). e) Find the CMRR value.

In an NPN transistor used as an amplifier, which components or connections  control the current flow between the  others?    Pick those that apply.     Either N-doped regions.     The base, symbolized by B controls the current between the emitter, symbolized by E, and the collector, symbolized by C.     The emitter, symbolized by E controls the current between the base, symbolized by B, and the collector, symbolized by C.     The P-doped depletion region.
