A new low voltage high-speed CMOS composite transistor is presented. It lowers supply voltage down to |Vt|+2 Vds,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 2µm N-well process with a 3 V supply are given.
