ABSTRACT:
A vector summation device includes a squaring circuit for receiving a number of input voltage signals, and a square-root circuit having first and second current terminals connected electrically to the squaring unit. The squaring circuit receives first and second current signals respectively from the first and second current terminals of the square-root circuit. The difference between the current values of the first and second current signals is proportional to the sum of the squares of the voltage values of the input voltage signals. The square-root circuit generates an output voltage signal with a voltage value that is proportional to the square-root of the difference between the current values of the first and second current signals.
