ABSTRACT:
A method and system to use voltage isolated and floating differential output amplifiers wired in series and parallel to achieve arbitrary output drive voltage and current for the applications load. Embodiments use multiple voltage-isolated and linearized devices to enable dynamically modifiable, Class A, Class B, and Class AB topologies of predetermined voltage and current performance. Embodiments can correct an output by linearizing one or more devices in a circuit by utilizing a linearization module (e.g., including one or more digital lookup tables, an error simulation circuit, or an equivalent) to linearize at least one parameter of at least one device in the circuit.
