Low-Power Four-Quadrant Multiplier Using Dual-Gate Transistors

چکیده
Abstract A four-quadrant analog multiplier using a novel type of GaAs transistor is presented. This device, called 2-D MESFET, is dedicated to low power and high speed applications[1],[2]. A special architecture for the multiplier was designed by taking advantage of the dual-gate structure of the 2-D MESFET. The circuit relies on the square algebraic identity [8], with the squaring operation realized by transistors in saturation. The fabrication of 2-D MESFET integrated circuits is still in its infancy but successful device prototypes have been fabricated and characterized, and accurate models for the device are available with AIM-Spice. Extensive simulations show correct functionality of the multiplier at high frequencies (30GHz) with low power consumption (0.5mW).
