  Diode-Based Temperature Measurement
  PDF, 44 Kb, 档案已发布: Sep 27, 2000
  Diodes are frequently used as temperature sensors in a wide variety of moderate-precision temperature measurement applications. The relatively high temperature coefficient of about -2mV/В°C is fairly linear. To make a temperature measurement system with a diode requires excitation, offsetting, and amplification. The circuitry can be quite simple. This Bulletin contains a collection of circuits

  Boost Instrument Amp CMR With Common-Mode Driven Supplies
  PDF, 175 Kb, 档案已发布: Sep 27, 2000
  Ever-increasing demands are being placed on instrumentation amplifier (IA) performance. When standard IAs can not deliver the required performance, consider this enhanced version. Dramatic performance improvements can be achieved by operating the input amplifiers of a classical three-op-amp IA from common-mode driven sub-regulated power supplies.

  Compensate Transimpedance Amplifiers Intuitively (Rev. A)
  PDF, 69 Kb, 修订版: A, 档案已发布: Mar 30, 2005
  Transimpedance amplifiers are used to convert low-level photodiode currents to usable voltage signals. All too often, the amplifiers have to be empirically compensated to operate properly. The problem can be easily understood if one looks at all the elements involved.

  Tuning in Amplifiers
  PDF, 44 Kb, 档案已发布: Oct 2, 2000
  Have you ever had the experience of designing an analog gain block with an amplifier that is specified to be unity gain stable only to find that it is oscillating out of control in your circuit? Or have you ever replaced a stable voltage feedback amplifier with a current feedback amplifier to find that the current feedback amplifier immediately oscillates when placed in the amplifier socket?

  Single-Supply Operation of Operational Amplifiers
  PDF, 77 Kb, 档案已发布: Oct 2, 2000
  Operation of op amps from single supply voltages is useful when negative supply voltages are not available. Furthermore, certain applications using high voltage and high current op amps can derive important benefits from single supply operation.

  Op Amp Performance Analysis
  PDF, 76 Kb, 档案已发布: Oct 2, 2000
  This bulletin reflects the analysis power gained through knowledge of an op amp circuit's feedback factor. Feedback dictates the performance of an op amp both in function and in quality. The major specifications of the amplifier descibe an open-loop device awaiting feedback direction of the end circuit's function. Just how well the amplifier performs the function reflects through the feedback inte
