An exchange of the amplitude axis for the time axis offers a possibility of overcoming resolution problems in analog-to-digital conversion in low-voltage CMOS circuits and/or of circumventing special resistor options in silicided processes. This exchange can be effected via some form of duty-cycle modulation. For its implementation a circuit configuration is described, consisting of an asynchronous sigma-delta modulator, followed by a phasesynchronized tapped ring oscillator which produces a poly-phase signal for sampling the asynchronous signal at a relatively low frequency. A detailed analysis is presented which accurately predicts the properties of the conversion scheme with respect to aliasing, quantization noise and nonlinear distortion. The results are illustrated with simulations of a design example.
A quantitatively verifiable expression for the Gravitational Constant is derived in terms of quantum mechanical quantities. This derivation appears to be possible by selecting a suitable physical process in which the transformation of the equation of motion into a quantum mechanical wave equation can be obtained by Einstein's geodesic approach. The selected process is the pi-meson, modeled as the one-body equivalent of a two-body quantum mechanical oscillator in which the vibrating mass is modeled as the result of the two energy fluxes from the quark and the antiquark. The quantum mechanical formula for the Gravitational Constant appears to show a quantitatively verifiable relationship with the Higgs boson as conceived in the Standard Model. keywords: gravitational constant; Higgs boson; quark model; pion; geodesic equation 1.IntroductionThe basic concept in quantum physics is the particle wave duality, which implies that a particle can dually be described by a mechanical equation of motion and by a quantum mechanical wave function. This wave function is the solution of a wave equation. The wave equation is obtained by a transformation of the particle's equation of motion in a way as conceived by Dirac [1]. Although Einstein's geodesic equation of motion [2] is the most generic of all, it is, so far, not adopted as the axiomatic base for the particle wave duality description. This is probably due to the mathematical complexity of 4D space-time. It is also the reason for the failure to unify quantum physics with gravity. Instead, Dirac derived his wave equation from the Einsteinean energy relationship of a particle in motion. Therefore, the equation is relativistic, but only special relativistic and not general relativistic. In this article I wish to develop the particle wave duality on the basis of Einstein's geodesic equation in 2D space-time and to compare it with Dirac's result. Next to that, I wish to motivate that the 2D space-time approximation is a justified modeling of a realistic physical process. This enables to relate gravity and quantum physics to the extent that the Gravitational Constant can be formulated as a quantitatively verifiable expression of quantum physical quantities. The concepts as will be outlined in this article, are invoked from previous work by the author [3]. Section 4 is devoted to a comparison of the 2D quantum mechanical wave equations as derived respectively by the geodesic approach (section 2) and Dirac's approach (section 3). This will result into an expression for the Gravitational Constant (section 5). In section 6 a physical process is selected that will deliver the quantity values. The result is subject to a relativistic correction (section 7). The final result is discussed in sections 8 and 9.The equations in this article will be formulated in scientific notation and the quantities will be expressed in SI units. Space-time will be described on the basis of the "Hawking" metric (+,+,+,+).

The mass differences between a charged pion and a neutral pion and between a charged kaon and a neutral kaon are calculated on the basis of a Higgs-type potential assigned to quarks. Moreover, an explanation is given for the mass spectrum of mesons. The results challenge the common view on quarks and the classification scheme of hadrons, and they support the validity of a classical field theory for quantum physics.

In this article the possible impact on the present state of particle physics theory is discussed of two unrecognized theoretical elements. These elements are the awareness that (a) the quark is a Dirac particle with a polarisable dipole moment in a scalar field and that (b) Dirac’s wave equation for fermions, if derived from Einstein’s geodesic equation, reveals a scaling theorem for quarks. It is shown that recognition of these elements proves by theory quite some relationships that are up to now only empirically assessed, such as for instance, the mass relationships between the elementary quarks, the relationship between the bare mass and the constituent mass of quarks, the mass spectrum of hadrons and the mass values of the Z boson and the Higgs boson.
The concept of a hypothetical particle with a field description as is commonly used for the Higgs particle allows relating quantum physics with general relativity. This results into an expression for the gravitational constant in terms of quantum mechanical parameters. In order to assign a quantitative figure to this expression, the field properties of the hypothetical particle are assigned to the pi-meson, which is regarded as the archetype of a two-body quark assembly. Furthermore it is shown that excited states of the two-body assembly are equivalent with the energetic ground state of the two bodies at reduced spacing. The mass equivalent of the ground state of the pi-meson relative to the mass equivalent of the first excitation appears to correspond with the mass ratio of muons and tauons.Résumé: Le concept d'une particule hypothétique dont la description du champ correspond à celle généralement utilisée pour la particule de Higgs, permet d'établir un rapport entre la physique quantique et la relativité générale. Cela conduit à une expression de la constante gravitationnelle en termes de paramètres de mécanique quantique. Afin d'étalonner cette expression dans le but d'obtenir une figure quantitative, les propriétés du champ de la particule hypothétique sont attribuées au pion, qui est considéré comme l'archétype d'une paire quark-antiquark. En outre, il est démontré que les états excités de cette paire ont des équivalents énergétiques de l'état fondamental. L'équivalent massique de l'état fondamental du pion comparé à l'équivalent massique de la première excitation semble correspondre au rapport de masse des muons et des tauons.
