  • IC Temperature Sensor Accuracy Compensation with a PICmicro Microcontroller
    Microchip Technology Inc. provides a number of analog and serial-output Integrated Circuit (IC) temperature sensors. The typical accuracy of these sensors at room temperature is within one degree Celsius. However, at hot or cold temperature extremes, the accuracy decreases non-linearly. Typically
  • Hot tips on IC temp sensors
    , the temperature-sensing material should keep the same temperature coefficient over its complete measurement range creating a linear response. Unfortunately, the temperature coefficient of most materials changes for different temperatures producing a nonlinear measurement. Many materials have
  • High-Speed Lithium Ion Battery Charger
    Driven by the need for untethered mobility and ease of use, many systems rely on rechargeable batteries as their primary power source. The battery charger is typically implemented using a fixed-function IC to control the charging current/voltage profile. The C8051F300 family provides a flexible

    cash for equity deal Samsung on SLC vs MLC flash memory How prices plunged after September calm ASML on immersion and Q3 results What analysts are saying about Lam Research Anadigics acquires assets of Celeritek subsidiary Strong growth predicted for the linear market Cypress beats 3Q forecast
  • Temperature Measurement Circuits for Embedded Applications
    will be compared with a frequency output RTD oscillator circuit, along with design examples using serial and analog output silicon Integrated Circuit (IC) sensors. In addition, a Programmable Gain Amplifier (PGA) circuit will be shown that can increase the effectiveness of the Analog-to-Digital Converter (ADC) bit
  • Protection For Switching Regulators
    Step down regulators are used to convert a higher DC voltage to a lower required DC voltage. Switching regulators offer higher efficiency than the linear regulators, excellent load step response and higher output currents. They are also more expensive than linear regulators and produce more noise
  • High-Voltage ICs
    types to be affected will be low-current versions in nonisolated applications. A high-voltage IC process is credited for the first major change in low-power supplies in 20 years. Single-chip supplies were, in the past, not feasible because breakdown-voltage barriers prevented conventional ICs from
  • MICRO:Analysis and Metrology-Yield Management, by F. Bergeret, p.59 (March '99)
    Fran cois Bergeret and Yves Chandon, Important benefits can be achieved by using well-known analytical methods--that is, the statistical analysis of data from databases. An investigation of problems that arose at the Motorola IC fab in Toulouse, France, demonstrated that data analysis methods
