发明名称 Method and apparatus for an efficient low voltage switchable Gm cell
摘要 A switching Gm cell allowing a wide transconductance range with a limited voltage range. The Gm cell includes a plurality of Gm setting devices, the operation of which is controlled by a Gm setting code. The Gm setting code is inputted into a switching circuit which turns on and off at least one of said Gm setting devices. Thus, coarse adjustments of the overall transconductance of the cell may be adjusted by changing the Gm setting code and fine adjustments may be made by utilizing the conventional method of adjusting a tuning voltage.
