The displacement of an object is measured using a linear potentiometer with resistance Rp = 1.8 k as shown in Figure A5. The potentiometer output is connected to a load with resistance R₁ through an operational amplifier circuit. The load is uncertain in a range [200 № -1 kN]. The input voltage Vin is 3.3 V. The total resistance element length is 250 mm. (a) Explain the operation of this circuit, including a justification for the operational amplifier stage. (b) Initially, the sliding contact is positioned such that X is one third of L.

One way to measure the slew-rate limitation of an op amp is to apply a sine wave (or square wave) as the input to an amplifier and then increase the frequency until the output waveform becomes triangular. Suppose that a 1-MHz input signal produces a triangular output waveform having a peak-to-peak amplitude of 4 V. Determine the slew rate of the op amp.

Figure QI shows the circuit diagram of a "Logarithmic Amplifier". In this circuit the feedback resistor of a normal inverting amplifier is replaced by a silicon diode. Since the current flowing through the diode increases exponentially with the voltage across the diode, the voltage across the diode will be proportional to the logarithm current flowing through it. Hence the output of the circuit is proportional to the logarithm of the input voltage.
