The display is a dominant power-consuming component in mobile devices. The active matrix organic light-emitting diode (AMOLED) display has been popular in mobile devices and its accurate power model is crucial for efficient power management. Existing power models do not consider the behaviours of the driving hardware components of AMOLED display modules. A new power model is proposed which considers...
A novel current-sensing technique with fast transient and high accuracy for a step-up DC–DC converter is presented. This circuitry is applied for sensing the current flowing through the equivalent series resistor (ESR) of the inductor to obtain the inductor current information. It is achieved with a fast transient response circuit (FTRC), an operational amplifier, a current-sensing stage and an overshoot...
