PARAPHASE CASCADE LOGIC DEVICE BUILT AROUND CMIS TRANSISTORS Russian patent published in 2003 - IPC

FIELD: digital computer engineering; logic multiposition binary data processing devices of metal-insulator-semiconductor integrated circuits. SUBSTANCE: each cascade 1, 2 uses paraphase inputs 34-37. Logic unit 10 has three types of key circuits 11-13 built around n-type transistors of which only one may be held closed. Newly introduced in stage is third inverter with relevant input connections to additional key circuit 13 and output connections to feed-through transistor 15 and to p-type transistors 7-9 of next stage. Device has output unit 3 made in the form of paraphase AND-NOR gate whose inputs are outputs of first and second inverters of each respective stage. EFFECT: enlarged functional capabilities of device. 1 cl, 2 dwg
