Abstract
A transconductance scaling circuit (500) includes an operational transconductance amplifier (504) having a tunable voltage, V.sub.tune2. A feedback loop controls the tunable voltage, V.sub.tune2, in response to the digital programming of the transconductance amplifier (504) and provides the tunable voltage as a current scaling output.
