Abstract:

 

A novel four-quadrant analog multiplier using floating gate  MOS (FGMOS) transistors operating in the saturation region is  presented.  The drain current is proportional to the square of the  weighted sum of the input signals.  This square law characteristic of  the FGMOS transistor is used to implement the quarter square identity  by utilizing only six FGMOS transistors.  The main features of this  remarkably simple multiplier circuit configuration are the large input  signal range equal to 100% of the supply voltage, nonlinearity of  0.0081%, bandwidth of 1.4--1.5 Ghz and THD of maximum 2.67%  (while the inputs are at their maximum values).
