Abstract
A voltage signal rectifier produces a rectified voltage signal from an input offset voltage signal. The voltage signal rectifier includes input offset, output, and reference nodes, two actively controlled current regulation elements (ACCREs), and two controllers. The input offset node is coupled to the input offset voltage signal. The rectified voltage signal is generated onto the output node. The reference node is coupled to a reference voltage for the input offset and rectified voltage signals. The ACCREs are coupled to the input offset node and one of the ACCREs is coupled to the output node. Each controller is configured to control the one of the ACCREs so that the ACCRE coupled to the output node allows current flow through it when the input offset voltage signal is higher than the rectified voltage signal and the other ACCRE is configured to allows current flow through it when the input offset voltage signal is lower than the rectified voltage signal.
