Abstract: Examples of circuitry and systems and methods provide a multi-way configurable amplifier to support various applications. The multi-way configurable amplifier may include a reconfigurable filter that comprises first and second inputs adapted to receive an input signal; a fully differential amplifier (FDA); and first and second reconfigurable resistance-capacitance (RC) networks. The FDA has an inverting input, a non-inverting input, an inverting output, and a non-inverting output. The inverting input is coupled to the first input, and the non-inverting input is coupled to the second input. The first reconfigurable RC network is coupled to the non-inverting output, and the second reconfigurable RC network is selectively couplable to the inverting output. The reconfigurable filter is configurable to enable operation in any of multiple modes including a single-ended mode of operation and a differential mode of operation.

Abstract: In an example, a dual-phase inverting buck-boost power converter for use with at least first and second energy storage elements includes an inverting buck-boost power converter and an inverting boost converter. In an example, the inverting buck-boost power converter is coupled between an input node and an output node of the dual-phase inverting buck-boost power converter and includes a first plurality of switches operable to couple to the first energy storage element, wherein the inverting buck-boost power converter is operable to supply a first load current. In an example, the inverting boost converter is coupled in parallel with the inverting buck-boost power converter between the input node and the output node of the dual-phase inverting buck-boost power converter and includes a second plurality of switches operable to couple to the first and the second energy storage elements, wherein the inverting boost converter is operable to supply a second load current.
