Integrated Digital Control Scheme for Fully Integrated High Frequency DC-DC Power Converter
A digital control scheme for fully integrated high frequency DC-DC power converter is presented in this paper. A resonant converter current mode control algorithm uses a varactor-based control to obtain a regulated output voltage. Control algorithm is based on an accurate estimate of output voltage response and a state machine-based formulation. Employing a current-mode approach simplifies computation nicely, enabling an efficient and effective control algorithm. Typical response time for voltage regulation is 430 ns for a 500 MHz system. Eight-bit data conversion is used in this design. The control system is built on TSMC 0.25 mum mixed- signal process. Simulation results verified the design.
