Abstract :
This paper describes a highly linear current four quadrant multiplier. The circuit is designed to operate in a fully differential way. It is based in the square-law characteristic of MOS transistors in saturation region. SPICE simulations with 2 μm CMOS parameters are shown that verify the operation of the circuit
