Title: Electrical circuits comprising master/slave bistable arrangements
IPC: H01L27/04
Filed: 1973-12-21
Abstract: 1494481 Transistor bistable circuits MULLARD Ltd 25 Nov 1974 [21 Dec 1973] 59462/73 Heading H3T [Also in Division H1] In a circuit comprising at least one master/slave bistable circuit, the slave bistable T2, T4 is supplied with bias from a fixed current source FCS, the master bistable T10, T12 is supplied with bias from a clocked current source CCS, and means T5 ... T8 are provided for providing the master, or that of a preceding or succeeding similar stage, with additional bias derived from the fixed current source. The clocked current source CCS switches between a first level, at which it equals the fixed current source and a lower level. Assume initially that CCS is at its high level and that the two bistables are in the state in which T2, T12 are conducting and T4, T10 are non-conducting, then in this state source FCS provides, via T5, a bias current to the base of T6 which is of an order of magnitude lower than that at the base of T2 and T12. In this condition, no base current flows in T8 since T4 is cut-off and the base of T7 is low, and the base current of T6 is restricted so that T6 does not saturate. When CCS switches to its low level, T6 diverts the base current of T12 until T12 cuts off, turning on T10. When CCS returns to its high level, T10 diverts the base current of T2 until this turns off switching on T4. The output at Q is therefore at half the input clock rate. In a modification, Fig. 7 (not shown) transistors T6, T8 are omitted and the collects of T5, T7 are connected to the opposite halves of the master bistable, i.e. T5 is connected to T10 and T7 to T12. In a further modification, Fig. 10 (not shown) the emitters of T9, T11 are also connected to the source FCS and the source CCS is applied via further transistors (T13, T14). The master/slave arrangement described may be employed as a JK, an RS or a D-type bistable, Figs. 11, 12, 13 (not shown) or as a stage in a shift register.

Filed: 1973-12-21
Abstract: 1415230 Matrix displays PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 Dec 1973 [8 Jan 1973] 59465/73 Headings G5C and G4H Gas discharge display apparatus comprises a display tube 1 with (1) a set of anodes 3, 5, 7 connected to output electrodes of a set of transistors 9, 11, 13, which have control electrodes connected to outputs 17, 19, 21 of a control circuit 23, and further electrodes connected to a supply terminal 25 at OV.; and (2) a set of cathodes 29, 31 ... 45 co-operating with anodes 3, 5, 7 and connected through capacitors 47, 51, 55 to output electrodes of a set of transistors 49, 53, 57, which have control electrodes connected to outputs 59, 61, 63 of a control circuit 65, further electrodes connected to terminal 25, and output electrodes connected via load impedances 86, 88, 90 to a supply terminal 83 at -50 v.; and via a switch (e.g. a transistor 85) which stops current flowing in the apparatus when the electrodes 3, 5, 7 are not energized. The load impedances preferably include transistors 87, 89, 91, connected as constant-current devices. The electrodes 29, 31 ... 45 are also connected via diodes 67, 69, 71 to a supply terminal 73 at - 130 v. Transistors 9, 11, 13, 49, 53, 57 of the MOS type form an integrated circuit 15 together with the control circuits 23, 65, which switch the transistors selectively to energize the electrodes so that a selection of the cathodes 29,31... 45 is energized, presenting an array of dots, segments &c. as required. In operation, if cathode 29 facing anode 31 is to light up, transistor 9 is made conductive and transistor 49 is cut off. The potential on anode 3 is high and is applied through resistor 75 to the base of transistor 85, which therefore conducts. Transistor 87 conducts, discharging capacitor 47 so that cathode 29 falls further in potential, cutting off diode 67. A discharge between anode 3 and cathode 29 occurs, and cathode 29 lights up, the discharge current remaining constant until it is extinguished by cutting off transistor 9 and turning on the transistor 49. Capacitor 47 is re-charged through diode 67. The anodes and cathodes could be interchanged in function, and the tube 1 could be divided into more than one discharge space or replaced by a plurality of tubes.

Title: Improvements in or relating to comparator circuit arrangements
IPC: H03F3/72
Filed: 1978-09-25
Abstract: A comparator circuit comprises a differential amplifier which is switchable from a stable to an unstable state, and vice versa. The differential amplifier comprises a balanced long-tailed pair of transistors Q1, Q2 which may be FETS with a field effect transistor (F.E.T.) Q3 having a channel connected between the collectors or drains of the long-tail pair and a gate connected to a pulse generator. The F.E.T. normally shorts together the collectors, but pulses from the pulse generator restore differential gain to the amplifier. During the presence of each pulse, a differential output signal is produced whose polarity depends on the imbalance in the differential inputs of the two halves of the long-tailed pair. With no input signal, random noise produces equal numbers of output pulses of each polarity. An input signal below the noise level is detectable, as it alters the pulse polarity distribution. <IMAGE>

Title: A method for manufacturing a semiconductor device
IPC: H01L21/3215
Filed: 1978-10-26
Abstract: A method for manufacturing a device such as an npn-type transistor includes steps of depositing or implanting phosphorus on or in a p-type region (11) to form a shallow n-type region, covering the deposited phosphorus with a poly-crystalline silicon layer (18) and heating the deposited phosphorus to diffuse it into the p-type region (11) to form an n-type region (17). Because phosphorus diffuses more readily into polycrystalline silicon than into mono-crystalline silicon the presence of the poly-crystalline layer (18) causes the diffused n-type region (17) to be shallow than if the layer (18) were absent. Various application of this effect are described. <IMAGE>
