to the circuitry of fig4 by cancelling the effects of cin and eliminating error currents due to icmr and dissimilarities created during processing fig6 shows the current feedback amplifier of fig4 with current mirrors 120 and 130 substituted with current mirrors 620 and 630 fig6 further shows an alternative method of providing compensation from the method shown in fig4 for convenience the circuitry carried over from previous figures is similarly labeled current mirrors 620 and 630 are wilson current mirrors which enable an increased output resistance from standard current mirror circuitry shown in fig4 the wilson current mirrors 620 and 630 each have an input branch formed by the collector and emitter of respective transistors 622 and 632 the collectors of transistors 622 and 632 typically form the input i in of current mirrors 620 and 630 similar to the collectors of transistors 122 and 132 in fig4 the current source i b is thus connected between the emitters of transistors 622 and 632 the emitters of transistors 103 and 104 are however connected to the input branch of current mirrors 620 and 630 at the emitter of respective transistors 622 and 632 such a connection providing advantages as described below an emitter resistor are provided between the emitter of transistor 622 to the positive power supply v while an emitter resistor is provided between the emitter of transistor 632 and the negative power supply v an output branch of the wilson current mirror 620 is formed by the collectors and emitters of transistors 624 and 626 while the output branch of wilson current mirror 630 is formed by the collectors and emitters of transistors 634 and 636 the collector of transistor 624 is connected to the emitter.
