Abstract
A position sensing system includes a linear variable differential transformer (LVDT) to provide a first output voltage and a second output voltage. The position sensing system also includes two precision rectifiers. Each of the precision rectifiers comprises only operational amplifiers and resistors and obtains the first output voltage or the second output voltage as an input and to provide a full-wave rectified output.
