Figure Q1 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.

Figure Q1
The current flowing through a diode is given by the Shockley Diode Equation:
=.
where
I, is the current flowing through the diode
q is the charge on the electron (given at the back of the examination sheet)
Vp is the voltage across the diode
K, is Boltzmann's constant (given at the back of the examination sheet)
T is room temperature (given at the back of the examination sheet)
Given that I,>>I; an approximate expression for V, as a function of I, is
Write (T) for truc or (F) for False for the following:
1. An ideal op-amp has very high input impedance.
2. A differential amplifier is the first stage in all op-amps.
3 If the same voltage applied to both inputs of op-amp, the mode of operation is called double-ended mode
.4 A practical op-amp has non-zero output impedance.
5. In zero level detector. the output changes state when the input becomes negative. 6. An averaging amplifier with 10 inputs has the ratio of R/ R is
Set up the opamp circuit that performs the following operation. Plot the outputs that appear in the processes for 20 ms. The feedback resistance will be taken as 10kΩ for all circuits. The supply voltage of the opamps that perform the first three operations is ±8 V. The supply voltage of the opamp or opamps in the post-process is ±5 V. In addition, the AC signals given from the inputs have a frequency of 100 Hz.
I would be very happy if you could be quick :)
