Low voltage high-speed CMOS square-law composite transistor cell

• A new low voltage high-speed CMOS composite transistor is presented. It lowers supply voltage down to \V-t\ +2V(ds,sat) and considerably extends input voltage operating range and achieves high speed operation. As an application example, it is used in the design of a high-speed four quadrant analog multiplier. Simulations results using MOSIS 2 mu m N-well process with a 3 V supply are given.
