Abstract
A wide bandwidth transconductance amplifier utilizing internal feedback is stabilized over a wide range of output currents. A compensation driver circuit senses the output current in the amplifier and feeds it back through a compensation capacitor. This keeps the bandwidth of the amplifier constant and optimally stabilized over a 16 to 1 range in output current. This compensation scheme eliminates compensation compromises that can limit the useful dynamic range of transconductnce amplifiers while offering a wide bandwidth low distortion transconductance with high output impedance over frequency.
