Filed: 1973-01-19
Abstract: 1382931 F.E.T. driver circuit ROCKWELL INTERNATIONAL CORP 19 Jan 1973 [14 April 1972] 2950/73 Heading H3T Input lines 6, 9, 10, 11, 12 (to a keyboard) are successively earthed through respective F.E.T.'s 3 of storage cells 3 (8) in response to coincidence of a common control signal S and a respective data signal on lines 19 to 23. These came from a R.A.M. decode matrix. A F.E.T. inverter 28 with bootstrap capacitance 27 to enhance conduction receives 5 and controls all the storage cells 2. Respective F.E.T.'s 25 feed data from 24 to the cells 2 (8). In # 1  time, if S is true then F.E.T. 28 conducts to turn on F.E.T.'s 15 and 30. F.E.T. 15 conducts its # 1  input to turn on F.E.T. 16 which earths capacitance 29, and through F.E.T. 32 biased on by V, a capacitor 33. F.E.T. 25 is off and so no potential is passed through F.E.T. 30. The storage cell is thus cleared or reset. In # 2  time, F.E.T. 16 goes off but F.E.T. 30 is still held on. F.E.T. 25 goes on in response to true data from the R.A.M. decode matrix 24 and supplies # 2+3  potential to node 31 and hence to capacitors 29, 33. Capacitor 29 consists of an inversion layer in a p-diffusion on an n-substrate overlaid with an insulated "gate" to which # 3  is applied; and it has negligible capacitance in the absence of applied potential. When node 31 is charged in # 2  time, while # 3  holds the "gate" electrode unchanged, the capacitance is formed and stores the charge at node 31. In # 3  time the gate of C29 is raised and this carries the gate of F.E.T. 34 sufficiently high to charge C33 to V, with no threshold drop across F.E.T. 34. This turns on F.E.T. 3 to earth line 6.
