Abstract: A COT (constant on-time) buck converter includes a first transistor, a second transistor, a driver circuit, an inductor, a first resistor, a second resistor, a capacitor, a load, and a feedback loop circuit. The feedback loop circuit includes a first switch, a second switch, an error amplifier, a comparator, a frequency locked loop circuit, an inverter and a COT logic circuit. The COT buck converter is able to improve DC (direct-current) regulation efficiency and transient response time.

Abstract: An electronic device is capable of determining a radio communications configuration. The electronic device includes a GPS module arranged for receiving an updated GPS coordinate. A controller is electronically coupled to the GPS module, and arranged for controlling the GPS module to receive the updated GPS coordinate and for determining the radio communications configuration based on the updated GPS coordinate received from the GPS module. A transmitter is electronically coupled to the controller and arranged for transmitting a message from the controller according to the determined radio communications configuration.
