With the rapid development of wireless power transfer (WPT), the self-resonant WPT system without using additional compensation capacitors has attracted attentions. However, most of reported self-resonant WPT systems have low power transfer (less than 100 W) and high operating frequencies at megahertz.
of the reset assures that it is properly timed and only occurs when needed. A generic view of a self-reset logic is shown in Fig 1. In the domino case, the clock is used to operate the circuit. In the self-resetting case, the output is fed back to the precharge
Self-discharge occurs because in the charged state a high potential (relative to the open-circuit potential, OCP) is held on the two EC electrodes (Figure 1).This high energy state will naturally relax by whatever …
In order to achieve high luminance uniformity, the pixel circuit compensates its Vth variation of the MOSFET for the driving transistor internally by using self-discharging method. Also presented are 0.5-in Quad-VGA and 1.25-in wide Quad-XGA microdisplays with the proposed pixel circuit.
