  Micropower Circuits for Signal Conditioning &mdash AN23
  PDF, 2.2 Mb, File published: Apr 1, 1987
  Low power operation of electronic apparatus has become increasingly desirable. AN23 describes a variety of low power circuits for transducer signal conditioning. Also included are designs for data converters and switching regulators. Three appended sections discuss guidelines for micropower design, strobed power operation and effects of test equipment on micropower circuits.

  Micropower Circuits for Signal Conditioning
  Jim Williams
  Low power operation of electronic apparatus has become
  increasingly desirable. Medical, remote data acquisition,
  power monitoring and other applications are good candidates for battery driven, low power operation. Micropower
  analog circuits for transducer-based signal conditioning
  present a special class of problems. Although micropower
  ICs are available, the interconnection of these devices to
  form a functioning micropower circuit requires care. (See
  Box Sections, “Some Guidelines for Micropower Design
  and an Example” and “Parasitic Effects of Test Equipment
  on Micropower Circuits.”) In particular, trade-offs between
  signal levels and power dissipation become painful when
  performance in the 10-bit to 12-bit area is desirable. Additionally, many transducers and analog signals produce +V inherently small outputs, making micropower requirements complicate an already difficult situation. Despite the
  problems, design of such circuits is possible by combining
  high performance micropower ICs with appropriate circuit
  techniques.

  Figure 1 shows a simple circuit for signal conditioning
  a platinum RTD. Correction for the platinum sensor’s
  nonlinear response is included. Accuracy is 0.25В°C over …
