Abstract
1384830 Shift registers HITACHI Ltd 23 Aug 1973 [25 Aug 1972] 40047/73 Heading G4C [Also in Division H3] A 4-phase dynamic shift register comprises two C-MOS logic circuits (see also Division H3) connected in cascade. In operation, when clock pulse # 1 reaches the "O" level, T 23 is turned off and T 21 conducts to charge an output capacitance C L and the parasitic capacitances associated with logic circuit LB 3 via T 22 . Subsequently when # 1 returns to the "1" level, T 23 is rendered conductive and the charge or discharge of C L is determined by the level of the input signal Vin to the logic transistor T 24 during the remainder of the period of conduction of T 22 . The second circuit functions in a similar manner during the # 3 # 3+4 periods. The FETs T 22 , T 32 may each be replaced by a pair of parallel connected FETs driven by separate clock pulse trains # 1 , # 2 ; # 3 , # 4 .
