ECE 2204 Electronics Fall 2009 Quiz #6 October 19 (Monday) Weight: 10 points Name (PRINT): K E Y ID # Circle correct ones. 1. ( TRUE FALSE ) A BJT is a three terminal device. 2. ( TRUE FALSE ) “Emitter” of a BJT corresponds to “Drain” of a MOSFET. 3. ( TRUE FALSE ) Two terminals of a BJT are geometrically identical. 4. ( TRUE FALSE ) A BJT meets a current relationship of IC = IB + IE. 5. ( TRUE FALSE ) An npn BJT meets a voltage relation of VC > VB > VE in forward-active mode, and a pnp BJT meets VE>VB>VC. 6. ( TRUE FALSE ) Base current of a BJT is always not zero in forward-active mode, but gate current of a MOSFET is zero in saturation mode. 7. ( TRUE FALSE ) IC = βIB is true for a BJT, and β is called common-emitter current gain. 8. ( TRUE FALSE ) VBE of a BJT in forward-active mode is equal to the diode turn-on voltage (typically 0.7 V). 9. ( TRUE FALSE ) A common emitter circuit amplifies the base current, not the base voltage. 10. ( TRUE FALSE ) A BJT has a finite output resistance ro.
