Patent ID: 7629847

Claim:
An opposing current (OC) differential amplifier circuit, comprising: a non-inverting circuit arrangement including: a first input section including a non-inverting input node operable to utilize a full input voltage; a first reference section coupled to the first input section and operable to apply level shifting and stabilized amplification; a first output section coupled to the first reference section and operable to amplify a first current into a load; an inverting circuit arrangement coupled to the non-inverting circuit arrangement and including: a second input section including a non-inverting input node operable to utilize a full input voltage; a second reference section coupled to the second input section and operable to apply level shifting and stabilized amplification; and a second output section coupled to the second reference section and operable to amplify a second current into a load, wherein the non-inverting and inverting circuit arrangements are operable to provide a small-signal differential gain of the OC differential amplifier circuit that is a function of transconductance of the input, reference and output sections.
