  • Models 441A and 441AL Frequency-to-Voltage Applications
    frequency-to-voltage conversion for almost any application.
  • Voltage-to-Frequency Analog-to-Digital Converters
    -to-frequency analog-to-digital conversion has a high degree of noise rejection, because the input signal is effectively integrated over the counting interval. Voltage-to-frequency conversion is commonly used to convert slow and often noisy signals. It is also useful for remote sensing applications in noisy
  • Circuit Ideas: High-efficiency dc/dc conversion
    a resonant-reset forward converter with synchronous rectification. It is frequently found in isolated industrial and telecom applications. A key component that determines conversion efficiency in these circuits is the resonant capacitor C . It facilitates zero-voltage turn-off of a MOSFET switch
  • AMETEK Introduces High-Frequency Chargers East Penn Introduces New Deka Unigy 12AVR170ET AMREL's New High Voltage Power Products
    AMETEK Prestolite Power has added the Prestolite Advanced Charger (PAC) Eclipse Series to its PAC 800 and Equinox TM lines of high-frequency battery chargers. The compact PAC Eclipse Series uses advanced MOSFET high-frequency power conversion circuitry to provide efficient, dependable battery
  • D/A Conversion Using PWM and R-2R Ladders to Generate Sine and DTMF Waveforms
    of complex analog waveforms.: (PWM and R-2R Ladder). Both the Pulse Width Modulation (PWM) and resistor ladders require only a few external components to create a D/A converter with the PICmicro? microcontroller series. These techniques can be used to generate dual-tone multiplexed frequencies (DTMF
  • Designing Power Supplies for Global Applications (.pdf)
    transistors-the two-transistor forward converter-can be used to provide low-cost, steady output voltages even when operating over a wide range of input voltages. (PWM) to provide high conversion efficiency. Such supplies are generally limited by the minimum pulse widths possible when using commercial PWM
  • Design and Development of Medical Electronic Instrumentation
    effort. We discuss analog-to-digital conversion. of physiological signals as well as methods for high-resolution spectral analysis. Projects. include a universal sensor interface, sensor signal conditioners, using the PC sound card as. a data acquisition card, voltage-controlled oscillator
  • Dealing With Noise Generated By A DC/DC Converter
    During the conversion process, all DC/DC converters generate unwanted high frequency noise. Over the years designers have used different designs and topologies to minimize and/or eliminate the noise in DC/DC converters. Independent of the design or topology used, cost and performance usually track
