    • Provided is a voltage-controlled oscillator (VCO) using a current feedback network for use in a wireless communication terminal. The voltage-controlled oscillator has high input impedance and low output impedance, so that a degree of isolation from the external load is excellent, thereby preventing degradation of the Q-factor by the load in overall oscillation circuit. In the voltage-controlled oscillator of the present invention, an LC resonator is provided to generate positive feedback, and negative resistance may be obtained at a wider frequency range by tuning a varactor of the LC resonator. And a boosting inductor is inserted into the positive feedback loop to have a greater negative resistance, therefore it is possible to prevent a problem in which the oscillation does not occur due to the parasitic resistance components generated during circuit fabrication.
    • 提供了一种使用电流反馈网络在无线通信终端中使用的压控振荡器(VCO)。 压控振荡器具有高输入阻抗和低输出阻抗,使得与外部负载的隔离度优异,从而防止整个振荡电路中的负载对Q因子的劣化。 在本发明的压控振荡器中,设置LC谐振器以产生正反馈,并且通过调谐LC谐振器的变容二极管可以在更宽的频率范围内获得负电阻。 并且将增压电感器插入到正反馈回路中以具有更大的负电阻,因此可以防止由于在电路制造期间产生的寄生电阻分量而不发生振荡的问题。

    • The present invention is based at least in part on the discovery of a role for the JNK signaling pathway in longevity. In particular, the present inventors have shown that modulation of the c-jun N-terminal kinase (JNK) signaling pathway in an organism, optionally in combination with modulation of the insulin receptor (IR) signaling pathway, can enhance longevity in an organism. Accordingly, the present invention features methods of identifying modulators of longevity in assays featuring organisms and/or cells having either a functional or deregulated JNK signaling pathway and, optionally, a functional or deregulated IR signaling pathway. Also featured is an in vitro method of identifying an agent capable of enhancing longevity featuring an assay composition having a JNK signaling pathway molecule and insulin signaling pathway molecule. Further featured are therapeutic methods for the use of JNK signaling pathway modulators to enhance longevity.
