Abstract :
A bipolar low-voltage quarter-square multiplier is presented. The proposed multiplier is very simple because the multiplier cell is built from four identical emitter-coupled pairs connected in parallel and its input system is realized using resistive dividers. Therefore, it is also very practical because it is easy to implement the circuit on a large scale integration (LSI). The fundamental characteristics at a 1 V supply voltage were verified on a breadboard using transistor-arrays and discrete components, it is, furthermore, very suitable for low-power operation
