differential input single-ended output opamp

What is a common mode gain?

The circuit diagram of step-up type DC-DC converter is given below. It is assumed that the output capacitor is large enough and the output voltage is constant. (Consider that there is no circuit losses.) Select an inductance value for the CCM operation state of the circuit. Assume that Output voltage (Vç) is regulated and prove that the circuit will always have to work at CCM operation state for maximum input voltage and minimum output current.

Explain under what conditions we should use a differential amplifier as well to do with differential amplifier advantage!

Calculate the differential voltage gain and the diff input resistance.

Identify a signal conditioner of transducer. Please explain briefly.

1. Suppose that you have a 12-bit, successive approximation register (SAR) A/D converter with a total conversion time of 100 microseconds (including sampling time). a). What is the maximum frequency of an analog signal that it can capture? b). Suppose that the converter can convert an input voltage over the range of 0 to +3.3V, what is the minimum voltage change that should be measurable by this converter? c). What is the quantization error of the ADC?
