Design of Ternary Iil Circuits Based on Theory of Grounded Current

According io the action principle of I2L circuits, this paper propcm t.he theory of grounded current. switches to describe the interaction between grounded transistors and currmt signals in I”L circuits. In this theory, switching stat.r of grounded transistor and current signal are dcwritcul separately by two different kinds of variables. b i d e s . t hmhitld coniparison operation and grounding *)ptmtion are intrrtducerl to connect t . h w two kinds of variables. Ha4 upon t.lir disrussions on the properties of opcratioiis and the synthesis of functions. the design proc c r l u ~ ~ for ternary 12L circuits with level restmat.ion is propml. Twnary I2L coriiplenient gate with level restoratioil aiwl tvrnar! quaatiwr are dtrsigntvl as esaiiiples. The rw i l ts Iiaw confirmcul that. t.his theory can lead to bet.t.er r l r i i p of 12i, rirrtrifs. lirrs [.he circuits simpler Lhan that, prr\ i t w l ! . prwc~iit.tul c x i i obtaind.
