Abstract
PURPOSE: To widen the amplitude of an output voltage at its maximum by adequately selecting the load resistance of an element which is large in ratio RON/ ROFF between ON resistance RON and OFF resistance ROFF.
CONSTITUTION: The DC equivalent circuit when switching elements are in two ON and OFF states is shown in the figure and the difference between output voltages VON and VOFF is logical amplitude VL. When the value of RON/ROFF is between 0.0001 and 0.5, the variation in VL is represented by curves (a) to (e) and the dotted line represents VL.max. Even if RON/ROFF is above 0.0001, selecting the load resistance within the range a half to twice as much as the value of RL where logical-amplitude maximum value VL.max can be obtained results in that more than 90% of maximum value VL.max can be obtained as the logical amplitude definitely. Therefore, the maximum logic amplitude can be secured by making load resistance RL a half to twice as much as the value of the right equation (I).
