Abstract

See full text

A high-frequency current source with a symmetric bipolar output stage piloted by an active bias network with an extended temperature range. The source is configured to provide a high impedance at 1 MHz and above. The invention includes such active EMI filters with such a high-frequency current source, for example in the current-sense current-inject feedback configuration.
