Abstract
An amplifier may include a gain stage configured to convert an input voltage signal to a current signal and to amplify the input voltage signal according to a gain. The amplifier may also include a buffer stage coupled to the gain stage at an internal node. The buffer stage may be configured to convert the current signal to an output voltage signal and to buffer the current signal from the gain stage so that a frequency bandwidth of the amplifier may be approximately maintained when the gain of the gain stage is increased.
