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. A second embodiment uses multiple matched voltage-isolated and floating differential output amplifiers in a single chassis to enable selection between a multi-channel amplifier and a high current and/or high voltage mono amplifier. A third embodiment uses a step-up transformer and paralleled unity-gain buffer amplifiers, on input and/or output stages, to produce a zero feedback, high performance, high drive amplifier. A fourth embodiment uses a high voltage unity-gain driver amplifier to bias a unity-gain buffer amplifier and its power supply to achieve an ultra low distortion high voltage buffer amplifier. A fifth embodiment uses multiple voltage-isolated and linearized devices to enable dynamically modifiable, Class A, Class B, and Class AB topologies of predetermined voltage and current performance. A sixth embodiment corrects 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.
