Abstract:
An amplifier stage comprising:a current source; a first differential transistor having a source, gate, and drain, wherein the source of the first differential transistor is coupled to the current source; a second differential transistor having a source, gate, and drain, wherein the source of the second differential transistor is coupled to the current source; a first series peaking inductor having positive and negative ends, wherein the negative end of the first series peaking inductor is coupled to the gate of the first differential transistor; a second series peaking inductor having positive and negative ends, wherein the negative end of the second series peaking inductor is coupled to the gate of the second differential transistor; a first output resistor having positive and negative ends, wherein the negative end of the first output resistor is coupled to the drain of the first differential transistor; a second output resistor having positive and negative ends, wherein the negative end of the second output resistor is coupled to the drain of the second differential transistor; a first shunt peaking inductor having positive and negative ends, wherein the negative end of the first shunt peaking inductor is coupled to the positive end of the first output resistor; and a second shunt peaking inductor having positive and negative ends, wherein the negative end of the second shunt peaking inductor is coupled to the positive end of the second output resistor.
