1. A DC coupled class AB transconductance block, comprising: first DC coupled transconductance stage operably coupled to produce a first differential current from a differential input voltage based on a first bias voltage; second DC coupled transconductance stage operably coupled to produce a second differential current based on the differential input voltage and a second bias voltage, wherein output current of the class AB voltage current converter is a sum of the first differential current and the secondary differential current; and biasing circuit operably coupled to produce the first bias voltage and the secondary bias voltage, wherein the first bias voltage is greater than the secondary bias voltage.
