A novel truncated squarer with linear compensation function

A truncated binary squarer is a squarer with a n bit input that produces a n bit output. The proposed design minimizes the mean square error of the squarer and results in a very simple and fast circuital implementation. The squarer, compared against state of the art circuits, provides a reduction of the mean square error ranging from 20% to 5%. At the same time, the proposed squarer is able to reduce the power dissipation, reduce the silicon area occupation, and increase the maximum working frequency. Implementations results are provided for a 0.18μm technology.
