    The Question is: Design and Build the BJT cct from the following specs. Given: Vcc=12V β=200 Ib=30μA Ve=0.1Vcc R2=0.1 Rin Vce=7V First I found Re Re=VRe/Ie VRe= Vcc x 0.1= 1.2V , Ie=(β+1) Ib=6.03mA Re= 199Ω Rc= VRc/Ic Vrc=Vcc-Vce-VRe=12-7-1.2=3.8 Ic= βIb =200 x 30μA =6mA = 3.8V/6mA=633.3Ω This is where I'm stucK. I learned how to Thevenize the Resistance and Voltage at the base but I am not sure if this is the right approach to use. If any one can help I would greatly appreciate it thanks Todd!

    Maybe a sketch of your bjt amp posted here would help our members to spot any possible flaws in your circuit.
