Anwendungshinweise

  • VCA8617: Response to Step-Change in Gain Control
    PDF, 102 Kb, Datei veröffentlicht: Mar 24, 2005
    The VCA8617 is an 8-channel variable gain amplifier ideally suited for portable and mid-range ultrasound applications. Each channel consists of a Low Noise Amplifier (LNA) and a Variable Gain Amplifier (VGA). The VGA contains two parts: a voltage-controlled attenuator (VCA) and a programmable gain amplifier (PGA). The PGA output feeds directly into an integrated 3-pole low-pass Butterworth filter.
  • AB-170: Ultrasound Processor Supplementary Material
    PDF, 752 Kb, Datei veröffentlicht: Jan 25, 2001
    An ultrasound system employs a multichannel phased array of acoustic elements to form an image. Previous implementation of this function has used bipolar technology. 0.5u CMOS technology has the advantage of lowering the cost and increasing functionality compared to using bipolar technology.
