Electronics (EE3C11)

he figure above shows the circuit diagram of a passive feedback transadmittance amplifier driving an inductive load and driven from a resistive source. The peak-peak value of the source voltage equals 1V and the maximum rate of change of the input voltage is ±1 V/μ s. Select the correct value of the peak-peak voltage at the output terminal of the operational amplifier. Rb = 200 ohm and L_l = 0.00025 [H] 

The figure above on the left shows the circuit of a negative feedback voltage amplifier with an operational amplifier. The amplifier is driven from a resistive voltage source with a source resistance of 100� and loaded with a 1k� resistor. The ideal gain of the circuit equals 10. The first-order, -3dB low-pass cut-off frequency of this amplifier should be at least 1MHz. At low frequencies the transfer should approximate the ideal gain within 0.1%. The noise figure of the amplifier for the given source should maximally amount 3dB.

The figure on the right shows the equivalent small-signal model of the operational amplifier. It has a DC gain A0�0, an input capacitance Ci��, one pole and a GB product GBGB.

Please select the valid set of minimum requirements for the operational amplifier and for R1�1 and R2�2 from the list below:
