Abstract
An apparatus for generating a steady state positive voltage (PVS) signal and a steady state negative voltage (NVS) signal is presented. The apparatus includes a bias signal generation module for generating a steady state reference voltage signal (RVS) based on a varying supply voltage signal (VDD), the RVS having a voltage level less than the PVS. The apparatus further includes a positive signal generation module (PSGM) generating the PVS, the PSGM including a first capacitor, the PSGM employing the first capacitor to generate a portion of the PVS based on the RVS. The apparatus further includes a negative signal generation module (NSGM) generating the NVS, the NSGM including a second capacitor, the NSGM employing the second capacitor to generate a portion of the NVS based on the RVS.
