  • Synthetic Inductor For Filters And Oscillators Is IR Controlled

    By Monika Sardana, December 23, 2002

    Almost all semiconductor products are sensitive to light, but this feature has been especially optimized for photodetectors (photodiodes and phototransistors). These are employed to sense or measure radiant energy in all industrial, consumer, and...

  • Use Multiplier Core For FM Stereo Multiplexed Transmission System

    By Monika Sardana, September 02, 2002

    A versatile four-quadrant analog multiplier core from Analog Devices, the AD633, is widely used in applications like modulation and demodulation, automatic gain control, power measurement, and voltage-controlled amplifiers. This wide spectrum of...

  • Versatile Shift-Keying Generator Uses Current-Feedback Amplifiers

    By Monika Sardana, June 24, 2002

    Digital information often must travel through analog channels in applications like satellite communication, digital cellular phones, digital microwave communication, and others. This transmission is made possible by the sinusoidal signal-modulation...

  • High-Q Bandpass Filter Is Well Suited To Current-Mode Signal Processing

    By Monika Sardana, March 04, 2002

    Analog signal processing has conventionally been viewed as a voltage-dominated form of design. But voltage-mode processing can restrict the system's dynamic range. There is also a limitation on the input range of signals for linear operation. An...

  • Universal Impedance Generator Handles Biomedical Applications

    By Saurav Gupta, December 03, 2001

    Components like inductors and capacitors constitute an integral part of filters and oscillators used for communication and biomedical applications. A common problem intrinsic to passive inductors is their enormous size as their value increases....
