Abstract: A controller for controlling a voltage converter includes a compensation circuit, an acceleration circuit and a driving circuit. The voltage converter generates a real-time charging current, a real-time battery voltage and a system voltage. The compensation circuit compares the real-time charging current with a preset charging current to generate a first comparison result, compares the real-time battery voltage with a preset battery voltage to generate a second comparison result, compares the system voltage with a preset reference voltage to generate a third comparison result, and generates a compensation voltage based on the first, second and third comparison results. The acceleration circuit adjusts the compensation voltage based on a state of charge of the battery and the system voltage. The driving circuit generates a first switching signal and a second switching signal based on the compensation voltage to control an upper switch and a lower switch of the voltage converter, respectively.

Abstract: A method for enhancing the performance of pentacene organic field-effect transistor (OFET): an n-type semiconductor thin film was set as a buffer layer between pentacene and polymer electret in the OFET with the structure of gate-electrode/insulating layer/polymer/pentacene/source (drain) electrode. The thickness of n-type organic buffer layer is 1˜100 nm. The induced electrons at the interface lead to the reduction of the height of the hole-barrier formed at the interface, thus effectively reducing the programming/erasing (P/E) gate voltages of pentacene OFET. The widened distribution region of positive space charges caused by ionized donors in n-type organic buffer layer effectively restricts the back-transfer of holes from polymer to pentacene, thus improving the performance of pentacene OFET, such as the P/E speeds, P/E endurance and retention characteristics.
