  • Regenerative tie-high tie-low cell
    Patent number: 6396306
    Abstract: A regenerative tie-high, tie-low cell (circuit) that provides unconditionally stable logic (1 and 0) output states used to tie off logic inputs. The circuit of this invention eliminates any current flow through p-channel/n-channel transistor pairs found in many conventional circuits and adds a regenerative transistor 42 to assure rapid response in achieving the proper logic output states. In one preferred embodiment, the circuit consists of only three CMOS transistors 40-42 that reduce the silicon area required, lowers the cost, and improves the overall reliability.
    Type: Grant
