19. 20. 21. 22. 23. 24. 25. 26. 27. 28. One I more than you can ever love yourself! HE is GOD! HE Cream IT Unijunction transister; a three-terminal single pajunction device that exhibits a negative resistance characteristic. TRUE FALSE The basic op-amp has three terminals not including power and ground: inverting (-) input, noninverting (+) input, and output. TRUE FALSE A differential amplifier forms the input stage of an op-amp. TRUE FALSE The ideal op-amp has infinite input impedance, zero output impedance, infinite open-loop voltage gain, and infinite bandwidth. TRUE FALSE A noninverting amplifier configuration has a higher input impedance and a lower output Impedance than the op-amp itself (without feedback). TRUE FALSE An inverting amplifier configuration has an input impedance approximately equal to the input resistor Ri and an output impedance approximately equal to the output impedance of the op-amp itself. TRUE FALSE The input bias current effect can be compensated for with external resistors. TRUE FALSE The closed-loop voltage gain is always less than the open-loop voltage gain. TRUE FALSE The internal Clag circuits also cause a phase shift between input and output signals. TRUE FALSE The gain-bandwidth product equals the frequency at which unity voltage gain occurs TRUE FALSE In an op-amp comparator, when the input voltage exceeds a specified reference voltage, the output changes state. TRUE : FALSE
