Unformatted text preview: ANS: 5. Consider the circuit shown in Figure p2.25. (a) Find an expression for the output voltage in terms of the source current and resistor values. (b) What value is the output impedance of this circuit? (c) What value is the input impedance of this circuit? (d) This circuit can be classified as an ideal amplifier. What type of amplifier is it? (See Section 1.9 for a discussion of various idealamplifier types.) ANS: 6. A certain internally compensated (dominant pole) op amp has a dc gain of 200,000 and 3 dB bandwidth of 5 Hz. Sketch the Bode plot of the magnitude of the open loop gain to scale. If this op amp is used in a noninverting amplifier having a closed loop dc gain of 100, sketch the bode plot of the magnitude of the closed loop gain to scale. Repeat for a closedloop dc gain of 10.
