    • Provided is an image sensor having a heterojunction bipolar transistor (HBT) and a method of fabricating the same. The image sensor is fabricated by SiGe BiCMOS technology. In the image sensor, a PD employs a floating-base-type SiGe HBT. A floating base of the SiGe HBT produces a positive voltage with respect to a collector during an exposure process, and the HBT performs a reverse bipolar operation due to the positive voltage so that the collector and an emitter exchange functions. The SiGe HBT can sense an optical current signal and also amplify the optical current signal. The image sensor requires only three transistors in a pixel so that the degree of integration can increase. The image sensor has an improved sensitivity of signals in the short wavelength region and a sensing signal has excellent linearity such that both a sensing mechanism and control circuit are very simple.
    • 提供了具有异质结双极晶体管(HBT)的图像传感器及其制造方法。 图像传感器由SiGe BiCMOS技术制造。 在图像传感器中,PD采用浮动型SiGe HBT。 SiGe HBT的浮动基极在曝光过程中产生相对于集电极的正电压,HBT由于正电压而执行反向双极性操作,从而集电极和发射极交换功能起作用。 SiGe HBT可以感测光电流信号,并且还可以放大光电流信号。 图像传感器在像素中仅需要三个晶体管,使得集成度可以增加。 图像传感器在短波长区域具有改善的信号灵敏度,并且感测信号具有优异的线性度,使得感测机构和控制电路都非常简单。

    • 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.
