If the Op-Amp in the figure is ideal, the output voltage V_out will equal to

Generally, the gain of a transistor Amplifier falls at high frequency due to the

The action of a JFET in its equivalent circuit can be best represented as a

Three identical amplifiers with each one having a voltage gain of 50, input Resistance of 1 KΩ and output resistance of 250Ω, are cascaded. The open circuit voltage gain of the combined Amplifier is
