Abstract
An output amplifier having a pair of controlled current generators each with an output impedance that is electrically connected to the other, a pair of output controllers each of which is across a corresponding one of the output impedances, and a pair of feedback impedances each connected from a corresponding one of the output controllers to a corresponding one of the controlled current generators. A differential amplifier is provided ahead of the controlled current generators with the amlifier input capacitively connected to the input of such differential amplifier. An offset adjuster is provided between the output impedances having its output connected to the capacitively connected differential amplifier input. A current feedback arrangement is provided between the output impedances and connected to the controlled current generators to be capable of altering currents generated thereby.
