This is an application note that introduces circuity for signal conditioning and power conversion designs
The document is an Application Note titled 'Circuitry for Signal Conditioning and Power Conversion Designs From a Once Lazy Sabbatical' by Jim Williams. It was published in March 1999 by Linear Technology Corporation. The note describes circuits that are refinements or adaptations of previous efforts, as well as other authors' works deemed appropriate.
The content covers categories including data converters, signal conditioners, transducer circuits, oscillators, and power converters. Specific examples provided include a micropower voltage-to-frequency converter with 0.02% linearity and 21uA supply current, and another version consuming only 8.8uA.
The circuit consumes a maximum of only 21uA.
It produces an output ranging from 0Hz to 10kHz.
At zero frequency, the current consumption is 2.1uA.
