BJT DC biasing for open circuit voltage gain of -10

[justinliu886]

Homework Statement

the signal Vsig has a maximum voltage amplitude +-100mv
Vcc = 15V, Rc = 2.2khom, Re= 200ohm, β= 100, Vf = 0.7V, Vce,min = 0.2V, VT = 25mV
Assume the Capacitor having negligible impedance for the signal’s frequencies.

Homework Equations

a. Choose the DC biasing voltage VBB to such value that the overall open circuit voltage
amplification A(VOC) = −10.
b. Will this amplifier work properly for the specified signal amplitude?

thx in advance!
