Current Amplifier Input Impedance at Zac Belmore blog

Current Amplifier Input Impedance. In figure 7.2.2 this is equal to \(r_b\) in parallel with the impedance looking into the base terminal,. Assuming a two input amplifier the signal current in both input probes is zero. The below diagram illustrates the model of an ideal current amplifier along with a practical one. Therefore, this same current (i1) must flow. Since the input impedance of the op amp is infinite, no current will flow into the inverting input. Notice the resistances at the input and output of a current amplifier in. Input impedance, zin or input resistance as it is often called, is an important parameter in the design of a transistor amplifier and as such. The ideal amplifier should not draw any current at all from its input. If the amplifier characteristics are satisfactory, we are assured that any required output signal level can be achieved with a small amplifier input current. Input impedance, \(z_{in}\), is defined as the ratio of \(v_{in}\) to \(i_{in}\).
