  15. Finding the input resistance of the difference amplifier.

  16. Representation of the common-mode and differential components of the input signal to a difference amplifier. Note that v1 = vCM - vd/2 and v2 = vCM + vd/2.

  17. (a) A popular circuit for an instrumentation amplifier. (b) Analysis of the circuit in (a) assuming ideal op-amps. (c) To make the gain variable, R1 is implemented as the series combination of a fixed resister R1fand a variable resistor R1v. Resistor R1fensures that the maximum available gain is limited.

  18. Open-loop gain of a typical general-purpose internally compensated op amp.

  19. (a) Unity-gain follower. (b) Input step waveform. (c) Linearly rising output waveform obtained when the amplifier is slew-rate limited. (d) Exponentially rising output waveform obtained when V is sufficiently small so that the initial slope (wtV) is smaller then or equal to SR.

  20. Effect of slew-rate limiting on output sinusoidal waveforms.
