Title: Field effect transistor logic circuit

Filed: 1973-04-19
Abstract: 1432810 FET logic circuits INTERNATIONAL BUSINESS MACHINES CORP 19 April 1973 [12 June 1972] 18983/73 Heading H3T In a FET logic circuit having source terminals of output FETs 40, 28 connected to output terminals 48, 52 for supplying V o  and V o , drain terminals of each output FET 40, 28 connected to a periodic voltage source V y  and positive feedback capacitors 62, 61 connected between the source and gate of each output FET so as to be responsive to conduction of an associated output FET 40, 28 for supplying a voltage Vx to the gate of the associated FET where V x >V TH , where V TH  is the FET threshold switching voltage, so that the output voltages Vo and V o  have values greater than V y -V TH ; FETs 18, 20 each have a source connected to a constant reference potential and a drain connected to the gate of a respective output FET 40, 28. The logic circuit shown uses P channel FETs. When a binary 1 represented by a negative signal is applied to the data input 14 together with the negative voltage X to inputs 12, 36 FETs 10 and 26 turn on and node 22 charges to a negative level and causes FET 18 also to turn on. Now the X signal returns to zero and FETs 10 and 26 turn off and the voltage at node 30 is discharged to ground through FET 18. The ground potential at 30 is applied to the gate of FET 20 which remains off. Next the Y signal applied to 38 goes negative and FET 40 is turned on and FET 28 is off. Normally the output terminal 48 would rise to the value of the Y signal less the threshold drop V TH  of FET 40. However the positive feedback path provided by capacitor 62 charges node 22 to a voltage value at least greater than the V TH  drop of FET 40 so that the output voltage Vo at 48 rises to a level equal to the value of the driving voltage of the Y signal. The positive feedback to 22 also turns FET 18 further on to ensure that node 30 is held at ground which is transmitted to provide a complementary output V o  at 52. When a binary 0 represented by O signal is applied to the data input 14 together with negative X inputs 12, FETs 10 and 26 conduct and node 30 rises to a negative value and causes FET 20 to turn on. Node 22 is at ground potential and when the X gating signals return to 0 FET 26 turns off. FET 20 remains conductive. Next the Y signal goes negative to turn FET 28 on and the output terminal 52 is driven to a level of the driving voltage of the Y signal by the positive feedback via the capacitor 61. The FET 20 is driven further into conduction so as to ensure that node 22 and the output terminal 48 is maintained at ground potential. The circuit can be constructed as an integrated circuit.
