Amplifier circuits that generate CM currents are provided. Amplifier circuits that generator DM currents are also provided. Fully differential current feedback amplifier circuits with separate CM and DM inputs are also provided. Such amplifier circuits combine the benefits of CFA designs, such as high slew rate and bandwidth, with independent control of DM and CM signals. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures and the claims.
