Patent abstract
Disclosed examples include amplifier circuits with a first stage to amplify an input voltage signal according to a first stage gain to provide a first stage output voltage signal, and a second stage to provide an amplifier output voltage signal. A bias circuit provides an amplifier bias current signal to a current mirror circuit coupled with the first stage to control a first stage bias current, and an adjustment circuit to reduce the amplifier bias current signal and increase the first stage gain when the input voltage signal is near a first supply voltage or a second supply voltage.
