  Design of Ultra-Low Power Circuits for Battery-Powered Wireless PIR Motion Detec (Rev. A)
  PDF, 479 Kb, Revision: A, File published: May 12, 2017
  In this document, a cost-optimized, ultra-low power op amp interface for wireless battery operated PIR (Passive Infrared) motion detectors is described. A single new 4-channel nanopower operational amplifier, TLV8544, implements the analog signal path, including two gain stages, two bandpass filters, and a window comparator.

  Cost-Optimized Opamp Window Comparator for Ultra-low Power PIR Motion Detectors
  PDF, 115 Kb, File published: Mar 6, 2017
  A window comparator is a combination of anoninverting and an inverting comparators along withtwo reference voltages. When the signal at the input of the windowcomparator crosses either thresholds, thecorresponding output changes state to an oppositevoltage level at the output.
