Topological Enhancements of Translinear Two-Quadrant Gain Cells
A method is proposed for extending the performance regime of two-quadrant translinear gain cells that can both increase the gain-control range and lower distortion, particularly at extremes of attenuation. The general operating principles of translinear cells are reviewed and a laboratory design for an enhancement of the current-steering cell is presented. The design is supported by a range of measurements to validate the technique.
