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.

TRUE OR FALSE1. Due to the infinite open-loop volatge gain of an ideal op-amp, its diferrential input voltage should approach zero for the output voltage to be finite.2. An op-amp is a voltage amplifier circuit with very high gain, very high input resistance, and a very high output resistance.3. The input resistance of an ideal op-amp is infinite resulting to the simplifying condition that the voltage at the non-inverting input is essentially equal to the voltage at the inverting input.4. For an op-amp differentiator circuit, if the input voltage is a sine wave then the output is also a sine wave that is in-phase with the input.5. The gain of a non-inverting amplifier can be adjusted to values less than 1 or greater than 1 by using appropriate values of the external resistors.

Four voltage sources of 3 V, 4V, 2V and 3V respectively are to be applied to the input terminal/terminals of “an" inverting amplifier. Design two different circuits for the two different cases with justified explanation and selection of proper resistances as per the requirements below: a) When an output of 4V is required (with phase shift). b) When an output of 8V is required (without phase shift) Note: Only inverting amplifier/amplifiers to be used for each case and all the voltage sources are to be used for each individual design as required in a) and b). 2.
