Abstract: 1366772 FET logic inverter circuits INTERNATIONAL BUSINESS MACHINES CORP 23 June 1972 [30 June 1971] 29416/72 Heading H3T An invertor I uses two complementary FETs 1, 2 connected in series with diodes 3, 4 between complentary phase lines #, #, and having their gates connected to a common input NO. When input NO is high, FET 2 is enabled and output NI goes low if ## is concurrently low. NI being low enables FET 1<SP>1</SP> of a complementary but otherwise similar inverter II, so that when 9 goes high FET 1<SP>1</SP> conducts to charge the output N2 to the high level. The two inverters constitute one stage of a shift register, one cycle of #, # being necessary to pass information from NO to N2. Dynamic operation uses the node NI capacitance (not shown) to temporarily store the level thereat, but regnerative feedback may be provided to give static storage. This involves a third, intermediate, inverter III similar to I but energized by different clock controls #<SP>1</SP>, #<SP>1</SP>. When #<SP>1</SP> is low and #<SP>1</SP> high (Fig. 4A, not shown) normal shifting operation occurs between I, II, &c., and III is ineffective. When # is high and #<SP>1</SP> low however, the level at NI (say, low) makes FET 12 conduct and the high #<SP>1</SP> level is applied to NO to maintain NI low. In an alternative static storage (latching) arrangement (Fig. 3, not shown), a third inverter (III) is again connected between NI and NO, but in this case it is identical to inverter I including the provision of the same clock controls #, #. The feedback however includes a gating FET (30) enabled by a further control # H  to establish regenerative feedback when required. Moreover, inverter II is low fed from the output (N3) of the third inverter (III) and not from NI. The diodes may be connected on the other side of their respective FETs.
