    摘要: The exemplary embodiments are related to systems and methods for a mode balanced parametric amplifier. Exemplary embodiments relate to a balanced parametric circuit including a first resonant structure including a first plurality of varactor diodes and a second resonant structure including a second plurality of varactor diodes. The first and second resonant structures are coupled to form a coupled structure having at least two orthogonal resonant modes, where a first resonant mode is resonant at a first frequency of an input signal and a second resonant mode is resonant at a second frequency of a pump signal. Further, the pump signal is used to one of amplify the first signal at the first frequency or mix and amplify the first signal to a frequency higher than the first frequency.

    摘要: Die Erfindung bezieht sich auf einen Mikrowellen- und Millimeterwellenmischer, bestehend aus zwei antiparallel angeordneten nichtlinearen Elementen. Der Mischer ist mit Wellenleitern aufgebaut, deren Abmessungen in Bezug auf die Frequenz der Pumpenergie (fp), Eingangsenergie (f E ) und Ausgangsenergie (f A ) so gewählt sind, daß die Pumpenergie (fp) und die Eingangsenergie (f E ) auf den Wellenleitern ausbreitungsfähig sind, die Ausgangsenergie (f A ) jedoch nicht ausbreitungsfähig ist. Ein solcher Mischer soll einerseits sehr verlustarm sein und andererseits mit sehr einfachen Filtern auskommen. Die Erfindung sieht hierzu vor, daß die Abmessungen des eingangs - (Abwärtsmischer) oder ausgangsseitig (Aufwärtsmischer) angeschlossenen Wellenleiters (1), beispielsweise eines Hohlleiters, so gewählt sind, daß die Frequenzen (f E ) oder (f' A ), nicht aber die Pumpfrequenz (fp) ausbreitungsfähig sind (Fig. 4).

    摘要: Embodiments of the present invention provide a device with an integrated low-noise parametric amplifier using a CCD-based structure with minimal noise gain. In one embodiment, a device which may be used for monitoring and/or diagnosing a human or an animal body comprises a CCD-based device including a first gate forming a first capacitor and a second gate forming a second capacitor, the first capacitor having a surface area larger than a surface area of the second capacitor; and a controller configured to input a signal to the CCD-based device; convert the input signal into a charge packet having a voltage associated therewith; transfer the charge packet from the first capacitor to the second capacitor of the CCD-based device, the voltage associated with the charge packet being multiplied by a ratio of the surface area of the first capacitor divided by the surface area of the second capacitor; and produce an amplified output signal from the multiplied voltage.

    摘要: An amplification circuit comprises a capacitor arrangement (42) and a switching arrangement. The capacitor arrangement has a first capacitor (C2) which has a voltage-dependent capacitance and a second capacitor (C1) (which may also be voltage-dependent). The circuit is operable in two modes, a first mode in which the input voltage is provided to one terminal of at least the first capacitor, and a second mode in which the switching arrangement causes charge to be redistributed between the first and second capacitors such that the voltage across the first capacitor changes to reduce the capacitance of the first capacitor, the output voltage being dependent on the resulting voltage across the first capacitor. The invention uses a voltage controlled capacitance in combination with charge sharing between capacitors, which has the result of providing a voltage amplification characteristic. This arrangement can thus be used for the amplification of an analogue voltage, or the boosting of a fixed level (i.e. digital voltage). Thus, the circuit of the invention can be used for level shifting or amplification, for example for use in the pixels of an active matrix array device.

    摘要: Dans la dérivation de pompe d'un amplificateur paramétrique qui en comporte trois, montées aux bornes d'une capacité non linéaire C(V), on monte un dipôle (D) à résistance négative, capable d'osciller à la fréquence fp ; on adapte les deux autres dérivations, l'une sur un circuit résonant (C s ), à forte surtension à la fréquence f s et l'autre, sur une impédance de charge, celle d'un circuit (C o ) résonant, à la fréquence f o . On a f o = fp - f s . Moyennant certaines conditions d'impédance, on recueille un signal à haut niveau sur f o . L'intérêt est que f o peut être sensiblement plus élevé que f s , par exemple 35 GHz contre 10 GHz.
