Abstract:
1. A current feedback amplifier circuit, comprising: a first input buffer ( a second input buffer ( first and second high impedance nodes ( a plurality of current mirrors to provide currents, proportional to sums of specific currents of the first and second plurality of currents, to the high impedance nodes; a first output buffer ( a second output buffer ( wherein the first plurality of currents are proportional to a difference between an input voltage provided to the first non-inverting input (IN+A) of the amplifier circuit and a fraction of its associated output voltage at the first output (OUTA); and wherein the second plurality of currents are proportional to a difference between an input voltage provided to the second non-inverting input (IN+B) of the amplifier circuit and a fraction of its associated output voltage at the second output (OUTB).
