IPC: H03F1/30

Abstract: 2.1 The quiescent current of a push-pull output stage is automatically adjusted by providing a sensing element in each branch of the output stage. The two voltages measured across the sensing elements with respect to reference potential are input to a differential amplifier stage, the output voltage of which is compared with a reference value with the aid of a comparator. The circuit exhibits a frequency-dependence of the automatic quiescent-current regulation due to the cut-off frequency of the output transistors used. 2.2 To avoid this frequency-dependence, a phase-rotating section is connected to one input of the differential amplifier, which worsens the common-mode suppression of the differential amplifier at high frequencies. The result of this measure is that the frequency- dependent error is compensated. 2.3 Push-pull output stages with quiescent-current control. <IMAGE>

Abstract: In various analog applications, it is desirable to have a known offset voltage at the input of a comparator, operational amplifier, or other type of differential stage. For example, in an ISDN receiver, the use of a desired offset allows for discriminating between signals having different amplitudes. In the present technique, a reference current, derived from a reference voltage ( V     ref   ) and on-chip resistor (R1) is used to set the currents through two input transistors, typically MOS transistors. An offset resistor (RO) in the source lead of one of the transistors produces a voltage drop that sets the offset at an input of the differential stage. The voltage drop across RO is proportional to ( V     ref    X RO)/R1. Since RO and R1 are fabricated by the same process, their ratio is independent of temperature, process, etc. Therefore, a well-defined offset is obtained.

Abstract: An improved fluid detection cable is capable of being dried easily after coming into contact with the fluid being detected and displays a measurable change in characteristic impedance immediately upon contact with the fluid. The cable comprises an inner conductor (1) and a cylindrical outer conductor (2) disposed in a substantially parallel and coaxial relationship with each other with a dielectric detection layer coaxially disposed between the inner and outer conductors (1,2). The outer conductor (2) is of an open braided construction which permits easy passage therethrough of the fluid to be detected. The detection layer comprises a pair of solid dielectric elements (3a,3b) stranded around the inner conductor (1) in a double helical configuration and defining an air gap between the two conductors (3a,3b) which is adapted to retain the fluid so as to measurably change the characteristic impedance of the cable. A coating (4) of dielectric material is provided around the solid inner conductor (1) the thickness of which can be controlled to adjust the change in characteristic impedance resulting from the presence of fluid within the dielectric layer. The improved cable construction allows the dielectric layer to be dried quickly even after the cable has been immersed in the fluid so that successive fluid detection measurements may be made without delay.

Abstract: The disclosed arrangement simulates the flow of control of an application program targeted for a specific instruction set of a specific processor by using a simulator running on a second processing system having a second processor with a different instruction set. The simulator reduces the number of translated instructions needed to simulate the flow of control of the first processor instructions by performing a graph analysis on the application program instruction flow of control to determine which condition codes of each instruction are not needed for a subsequent instruction and pruning the same from the translation so that fewer translated instructions are needed if the condition codes for an instruction are not set or used subsequently.
