AN2141 - PSoC® 1 Glitch Free PWM

Last Updated: 12/11/2012
Version: *A


PSoC digital blocks can operate as 8-bit pulse width modulators (PWM). Due to the special design of the PSoC, these modules do not incorporate glitch-free hardware logic but instead logic must be considered in software. This document presents a solution with a first-order predictor adequate to precisely generate any function.
