    A technique is described for achieving low-voltage offset and thermal drift in a monolithic integrated differential amplifier. First order compensation is achieved, under severe restrictions, for a simple differential pair. An alternative balancing technique utilizes the linear combination of two equal and opposite drift characteristics to minimize drift from all sources. Drift values of /spl plus...

    Precision monolithic circuit functions can be fabricated if proper circuit and processing techniques are incorporated. Compatible thin-film-on- silicon technology is coupled with annealing of individual resistors with a focused laser beam to provide a means for fabricating monolithic circuits in the 0.1 to 1.0 percent accuracy range. It is shown that special circuit techniques, which accommodate u... View full abstract»

    There is a growing demand for integrated operational amplifiers that combine high gain with a large unity-gain bandwidth and a simple frequency compensation. A frequency-compensation technique is described that enables construction of multi-stage amplifiers without introducing compensation problems. The suggested solution is based on the elimination of stages in the high-frequency region, such tha... View full abstract»

    Precision dc-coupled amplifiers having risetimes of less than a nanosecond have recently been fabricated using the monolithic planar process. The design is based on a simple technique that has a broad range of applications and is characterized by a stage-gain- bandwidth product essentially equal to that of the transistors, and a very linear transfer characteristic, free from temperature dependence...

    This paper describes a technique for the design of two-signal four-quadrant multipliers, linear on both inputs and useful from dc to an upper frequency very close to the f/SUB t/ of the transistors comprising the circuit. The precision of the product is shown to be limited primarily by the matching of the transistors, particularly with reference to emitter-junction areas. Expressions are derived f...

    A complete series voltage regulator circuit capable of delivering /SUP 1///SUB 2/ ampere of current has been built on a single 63/spl times/66-mil die using the conventional all- diffused processing technology. Improved performance has been achieved by using an internal low-power voltage regulator to supply the desired dc output voltage reference directly to a second main regulator. This permits t...

    The major difficulty encountered in the operation of a bipolar IC-directly from the ac line is the maintenance of back bias on the substrate isolation junction. The circuit power supply is derived by rectification of line voltage with diodes contained in the pellet. Because of the direct connection to the ac line no negative potential reference point exists and the substrate isolation junction bec... View full abstract»

    Temperature sensitivity of frequency of a monolithic RC oscillator can be separated into effects due to the passive frequency determining elements, the amplifier gain level, and the amplifier nonlinearity. Studies and experimental results of typical integrated oscillators indicate that accurate evaluation of performance can be obtained and lead to a method to achieve temperature compensation. A co...

    A certain correlation exists between the stability of a monolithic amplifier and to the product of the forward gain and the reverse transfer. Although a general method for determining stability cannot be given, it appears that instability problems are caused by output current rather than by output voltage. View full abstract»

    An integrated bridge network of four transistors is used as a self-neutralized active element in tuned RLC amplifier designs. The bridge network compensates for the transistor collector-base junction capacitance (C/SUB c/), yielding a 95-percent reduction in the common-emitter reverse transmission admittance. IF amplifier stages that achieve the maximum unilateral power gain of a common-emitter tr... View full abstract»

    Higher orders of complementarity of MOST circuits are obtained when the devices used differ not only in the dominant charge species, such as in n-channel and p-channel units, but also in the mode of control of channel conductance, such as in depletion mode and enhancement mode. Some of these circuits in a `hook' connection displayed unusual static volt-ampere characteristics, with `double points.'... View full abstract»

    An analysis is given for a photoparametric up-converter system. The up-converter consists of a single triplate line with one coaxial output connected to a circulator, through which the pump is applied and the signal extracted. The other end of the line is connected to the photo diode via a small coupling capacitor. The light is modulated at frequencies from a few hertz to some upper limit determin... View full abstract»

    Previous automatic gain-control configurations have not provided an entirely satisfactory solution to the dilemma of maintaining a high signal-to-noise ratio (S/N) with low distortion in low Q audio applications. A gain-control configuration that provides broadband control at a relatively high signal level with low distortion is described. View full abstract»

    From a linear analysis of a tunnel diode loaded with a transmission line, it is shown that oscillations highly stable in frequency are possible. Preliminary experimental results are in agreement with the theory. Stability on the order of one part in 10/SUP 5/ is easily attained. View full abstract»
