It is understood that the voltage comparators can utilise either a no-feedback (open-loop) operation or a positive-feedback operation. The op-amp LF411 is a high-speed comparator and for a circuit utilising it (shown in Fig. A2c), assume that an input (Vin) with 10 V peak amplitude at 1 Hz frequency is being applied. Please describe and draw the comparator output (Vo) by clearly labelling axes, threshold voltages and the saturation voltages in your sketch. Also show any supporting calculations including the calculation of Vref at the non-inverting terminal. 15 V LF411 +, Vout 20 kn 15 V Vin 5 V 10 kQ

Q2/B)- Show the connection of three combination op-amp stages ( Parallel and series connection) using an LM348 IC to provide outputs that are 110, 400, and 2601 times larger than the input. Use a feedback resistor of Rf = 500 kN in all stages, while can use only (R= 50 kN for first stage), (R= 25 k2 for second stage), and (R= 10 k2 for third stage)
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.
