    Summary form only given, as follows. The avalanche mode of operation for junction transistors is encountered at higher-than-normal collector voltages. In this avalanche region of operation the electrical character of the junctiontransistor is profoundly altered because of a voltage sensitive current-multiplication occurring at the collector junction. Current controlled N-type negative resistance c... View full abstract»

    Drum recording is accomplished bypassingcurrent through a magnetically soft write head placed in close proximity to a magnetically hard drum surface. Flux from the head resulta in magnetized areas on the drum surface. Drum coatings and heads presently in use require writing currents in the order of 1 ampere. Head impedances are typically 2 to 5 ohms. This means the writing circuit must supply seve... View full abstract»

  • Large scale testing of switching speeds of junction transistors

    Publication Year: 1957, Page(s): 7
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (205 KB)

    This paper describes a method of rapidly evaluating the switching speed of transistors by means of a fully automatic tester suitable for factory use. A transistor may be plugged into the tester and after a brief settling time, a voltage proportional to the expected switching speed appears on a meter or permanent recording device. Because of the non-linear nature of transistors, the test is restric... View full abstract»

    This paper reports the results of a number of tests made on a group of PNP alloy junction transistors whose power rating at the usual operating temperature is 30 milliwatts and whose cut-off frequency is about 3 megacycles. The tests show that as the temperature of the transistor is lowered, both the maximum power dissipation and the cut-off frequency are increased, thus making it possible for the...

    Summary form only given. It is known that the operating point of a transistor has a tendency to shift with temperature. An analysis is made of the factors contributing to this shift. It is found necessary to define two stability factors for an adequate formulation of the bias problem. The se factors, together with the voltage and current defining the operating point, are used in the design of bias... View full abstract»

  • Millimicrosecond transistor current switching circuits

    Publication Year: 1957, Page(s): 11
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (196 KB)

    If transistor switching circuits are to be developed having response times limited by the bandwidths of the transistors operating as amplifiera and by diffusion or transit time delay, it becomes necessary to avoid operation in saturation. Since a low collector-to-base voltage has a detrimental effect on transistor bandwidths, it is desireable, as well, to avoid operation near saturation. A techniq... View full abstract»

    Summary form only given, as follows. The complementary pair family of circuits can yield great economy in digital computer design, as has been shown in the preceding paper. One member of this family is attractive, because of its simplicity, in those situations where the ultimate in speed and load handling capacity is not required. If it were possible to allow saturation in the transistors, a very ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (45 KB)

    Summary form only given. A transistor monostable circuit using complementary transistors is described. The unique property of transistors in this application results in certain advantages compared to the transistor monostable circuit directly analogous to a tube monostable multivibrator. These are: 1. Higher inherent charge to discharge ratio (Le., faster recovery time) for the timing capacitor. 2... View full abstract»

Choice of feedback circuit configurations for the stabilization of amplifier circuit transconductance, transresistance, and current gain are discussed in terms of an idealized phase-reversing amplifier.

    Summary form only given. Essential to good sweep linearity in a bootstrap sweep generator is high input impedance and a gain which is close to one in the unity gain isolation amplifier which is used. It is shown that an emitter follower circuit is capable of providing a gain which is very close to unity due to the inherently high transconductance of a transistor. A method of bootstrapping the coll... View full abstract»

    Summary form only given. This paper describes the use of transistors in phase regulated power supplies. This type of power supply, which has been implemented previously with thyratrans, theoretically entails no dissipation in the regulator circuits. The regulator transistors are operated as rectifying switches whose conduction phase with respect to the ac supply voltage can be controlled over a 90... View full abstract»

    Summary form only given. The requirements for an oscillator may be met in a low-power feedback circuit rather than in the high-power output circuit. A small saturable transformer is used to supplythe transistor drive requirements in the improved squarewave oscillator circuit. The feedback transformer derives its primary power for sufficient positive feedback from the output circuit either as a vol... View full abstract»
