Abstract
An amplifier output is biased to optimize performance characteristics such as gain and output voltage. A temperature-independent current is subtracted from a temperature-dependent current. The difference is injected at the amplifier output to bias the amplifier output such that performance characteristics are enhanced. An additional amplifier stage may be used to prevent the bandwidth performance of the amplifier from being affected by the current injection.
