Title: Electrical shift registers
IPC: H03K3/315
Filed: 1961-02-03
Abstract: 894,180. Semi-conductor bi-stable circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 3, 1961 [Feb. 8, 1960], No. 4100/61. Class 40(6). [Also in Group XIX] A shift register uses Esaki diodes E 1 <SP>1</SP>, E 2 <SP>1</SP>. . as storage elements connected together through inductances L 1 <SP>1</SP>, L 2 <SP>1</SP>.., and a clock pulse applied to one of the elements biases it to one stable state whereas a clock pulse together with an information pulse switches the state of the element. In Fig. 5 a two-phase clock pulse system, comprising Pulses IA<SP>1</SP>, IB<SP>1</SP> applied to alternate elements of the register, is used. A conventional diode D 1 , D 2 . . is connected between the tunnel diode E 1 <SP>1</SP>; E 2 <SP>1</SP>. . and the inductance L 1 <SP>1</SP>, L 2 <SP>1</SP>. . . When 1 A <SP>1</SP> is applied to E 1 <SP>1</SP> the Esaki diode attains the state P<SP>1</SP> (Fig. 4). If IA<SP>1</SP> and a signal pulse <SP>i</SP>1n is applied to E 1 <SP>1</SP>, the state Q<SP>1</SP> is reached. Curve 16 is the load characteristic of a constructional diode alone, while curve 18 is the load characteristic of the diode in series with the next Esaki diode. The current through L 1 <SP>1</SP> is IR<SP>1</SP>-iQ<SP>1</SP>. When the clock pulse IB<SP>1</SP> is applied to E 2 <SP>1</SP>, L 1 <SP>1</SP> discharges and the sum of the currents through E 2 <SP>1</SP> is sufficient to switch it to Q<SP>1</SP>. An arrangement is also described (Fig. 2 not shown) in which resistances replace the diodes D 1 , D 2 .., and which necessitates the use of a three-phase clock pulse, information being applied to the middle Esaki diode of a group of three. Fig. 7 shows an arrangement using diodes and inductances, and employing only a single clock source, the clock pulses having an amplitude -IR<SP>11</SP> to +IR<SP>11</SP>. Information is entered on input <SP>i</SP>1n and the effect of the circuit is to cause L 1 <SP>11</SP> to discharge through E 2 <SP>11</SP> as the clock pulse reaches -I R <SP>11</SP>. The inductances may be replaced by capacitors, when successive Esaki diodes are opposed and the clock pulses are of alternate opposite polarities.
