Design technique of I2L circuits based on multi-valued logic

  • Wu Xunwei 
  • Hang Guoqiang 


This paper proposes the use of the current signal to express logic values and establishes the theory of grounded current switches suitable for I2L circuits. Based on the advantage that current signals are easy to be added, the design technique of I2L circuits by means of the multi-valued current signal is proposed. It is shown that simpler structure of I2L circuits can be obtained with this technique.
