Embedded System

On Figure P4a, you have a Common Emitter (CE) NPN BJT amplifier. Notice (unlike the circuits that we have studied in class) the absence of a source resistor R sig and load resistor R,. If we know how this L·amplifier behaves without Rsig and R, we can infer its behaviors if Rsig and R, were to be added.

You are to design the amplifier circuit on Figure P4a, i.e., find appropriate values for RB,, RB,, Rc,and R.Such that the voltage gain of the ampliifier

\left|\boldsymbol{A}_{\boldsymbol{v}}\right|=\left|\frac{\boldsymbol{v}_{\boldsymbol{p a t}}}{\boldsymbol{v}_{\boldsymbol{s} \boldsymbol{q}_{g}}}\right| \geq \mathbf{2} \mathbf{V} / \mathbf{v}

You are to design the amplifier circuit on Figure P4a, i.e., find appropriate values for RB,, RB,, Rc,and RE, such that the voltage gain of the amplifier  Verified     ### Question 26890  Embedded System
