Name:_________________________________ EE 3220 Test  SSN:___________________________________ Summer 2003 DO NOT WRITE ON THE BACK OF THESE PAGES. 1.) Design a BJT current source to produce 2mA for a differential amplifier,  given V EE  = -10 V.  What is total DC power absorbed by all components in  the current source?  2.) Design a BJT current mirror to produce 2mA for a differential amplifier,  given V EE  = -10 V.  What is total DC power absorbed by all components in  the current source?

3.) IF a differential amplifier requires 2mA for proper DC biasing, design a  BJT Widlar source that will produce this current. Given V EE  = 10 V.  What  is total DC power absorbed by all components in the current source?  4.) Find the two-port equivalent model for the circuit below.  This includes  finding r in , r out , a v , and V BIAS
5.) Compute the DC current produced by the FET current mirror below.

Unformatted text preview: 6.) Compute the power delivered to the load for this cascaded amplifier network. How could the power delivered be improved further? 7.) What is the swing range and maximum differential mode signal that can be applied without distortion for the differential amplifier below? 8.) Find the DC bias point, gain and output resistance for the voltage follower below. 9.) Explain the advantage of using a BJT (with a resistive load) for signal amplification over an FET with a resistive load. 10.) What are the advantages and disadvantage of adding a resistor to the emitter of a BJT amplifier? 11.) What uncontrollable factors affect β F of a BJT? 12.) What are two major effects that need to be considered if an FET’s V SB ≠ 0?...
