You are tasked with designing a linear amplifier using an NPN BJT for the circuit shown below. This means the transistor iv curves apply here. The voltages given are Vcc = 14 V and Vs = 1.0 V. The datasheet for the transistor says VBE (ON) = 0.7 V,VCE (SAT) = 0.2 V, and ß = 400. The design should have ic = 12 mA and VCE = 8 V. Find the resistances Rb and Rc that give the required ic and VCE. Vs H Rb M d VBE Rc VCE Vcc
