Design theory of digital circuits at switch level
Xunwei Wu · 1996
By analysing problems in the traditional design theory of digital circuits it is proposed that both switching variable and signal variable should be adopted for describing the switching state of internal elements and signal in digital circuits respectively.Based on the above viewpoint the switch-signal theory is established.According to the working principle in CMOS circuits,the related design technique at switch level is developed.By using the practical design examples it is shown that the circuits designed at switch level have simpler structures than their counterparts designed at the traditional gate level since the switch transistors are used as construction units in designs.
