| This thesis explores the implementation of noise filtering in low dropout voltage regulators (LDO), focusing on low-frequency noise types such as flicker and thermal noise. Flicker noise arises from impurities in the conductive channels in the circuit, resulting in low-frequency noise within the electronic components, and thermal noise is generated by the thermal agitation of charges. Filtering them is crucial for enhancing the performance and accuracy of electronic devices and communication systems.The research includes developing an algorithm to optimize the noise filtering capabilities of the circuit and evaluating two LDO circuits designed specifically for this application. The first circuit was a reference circuit, unoptimized for noise filtering. The second circuit was designed by incorporating the noise filtering algorithm to test its impact on output noise compared to reference. The algorithm instructs us how to choose the control parameters of the circuit in order to achieve near optimal noise-filtering performance. The results confirmed the feasibility of incorporating the algorithm to achieve efficient low-frequency filtering. |
