Abstract

A bias voltage source for a differential circuit has low output impedance at DC, but considerably higher output impedance within the frequency band of the differential signal being processed, to provide an accurate, well-matched common- mode bias voltage to each component of a differential signal path, while providing a low noise current, minimizing the conversion between common-mode and differential modes, and preserving available headroom, and all without requiring the use of large resistors.
