This work is based on a premanufacturing evaluation of a capacitance switch array (CSA). The main idea of this study is the replacement in a digitally temperature-compensated crystal oscillator (DTCXO) of the usual compensation system composed of a digital analog converter coupled with a varactor, in order to decrease the total power consumption and the supply voltage.
