Two-Quadrant CMOS Plug-in Divider

摘要

A two-quadrant CMOS current-mode plug-in divider using a compact 1/x device is presented. The mismatch errors of 1/x device cancel part of mismatch errors of the proposed divider. The simulation results indicate that the plug-in divider is feasible by the proposed approximation method. The adjustable 1/x device could be applied in difference ranges.
