摘要
An amplifier circuit and method for reducing bias noise is disclosed. The amplifier circuit includes a passive biasing source for supplying a desired bias signal to the amplifier and an active biasing source for energizing the passive biasing source to supply the desired bias signal. The amplifier circuit also includes a decoupler for selectively decoupling the active biasing source from the passive biasing source when the amplifier is configured for amplifying an input signal so that the amplifier remains isolated from electronic noise produced by the active biasing source while still being supplied the desired bias signal by the passive source.
