Latest Patents

David holds a patent for a system and method for enhancing bandwidth of low-dropout regulators using power transmission lines for high-speed input-output drivers. This invention addresses the issue of power supply rejection (PSR) peaking in low-dropout (LDO) voltage regulators, which can lead to reduced bandwidth and efficiency. The new design method combines power transmission lines (PTL) with LDOs to improve their bandwidth and efficiency. This approach is particularly applicable for LDOs regulating high-speed I/O drivers. The PTL, along with decoupling capacitors on the package or board, mitigates the PSR peaking. Testing has shown that this methodology results in approximately 80% lower power supply noise compared to conventional approaches.
