ABSTRACT:
A wide dynamic range transconductance stage has two branches, each branch being composed of a plurality of transconductance circuit paths. Each circuit path has a greater transconductance than the other circuit paths for its branch within a respective sub-range of the input signal range for the stage as a whole, with each path dominating the other paths for its branch within its respective sub-range. The overall bandwidth for the stage, its g.sub.m, its noise characteristics and its input voltage range are enhanced as a result. Bandwidth and slew rate may be independently optimized by the designer. Two paths are used for each branch in the preferred embodiment, with one path consisting of a bipolar transistor and the other path either a field effect transistor or a resistor degenerated bipolar transistor. Multiple paths may be used based on the same principle.
