Patent ID: 7466198

Claim:
A differential amplifier comprising: at least one current mirror; at least one differential pair; at least one cascode; at least one differential gain boosting amplifier for differential current mirror voltage control; and at least one common mode amplifier comprising a common mode voltage to control an output common mode of said at least one differential gain boosting amplifier, wherein the common mode voltage comprises a mirrored bias voltage, wherein the mirrored bias voltage feeds directly into said at least one common mode amplifier, wherein a differential input voltage feeds directly into said at least one differential gain boosting amplifier and said at least one differential pair, wherein a gain of said at least one current mirror is boosted by said at least one differential gain boosting amplifier, wherein a differential output voltage is indicative of said differential input voltage with an increase in gain, and wherein said differential output voltage is connected to said at least one cascode.
