Abstract
A buffer employs an input stage with an active, LC load. The active load includes integrated inductors that combine with the parasitic gate capacitances of a pair of transistors in a negative-transconductance (−Gm) booster configuration. The resulting active load emphasizes a desired frequency, improving the quality, or “Q,” of the input stage, and consequently of the entire buffer.
