20110074614 | BOOST CIRCUIT - A boost circuit is provided, which is configured to receive a bitstream signal, to boost the amplitude of the bitstream signal thus received, and to output the bitstream signal thus boosted. A first clock booster receives a clock signal, and boosts the amplitude of the clock signal. A second clock booster receives an inverted clock signal, and boosts the amplitude of the inverted clock signal. A switch receives the output signals of these two clock boosters, and selects the one output signal that is high level. A first capacitor is coupled to the output terminal of the switch. A level shifter level-shifts the high level of the bitstream signal to the voltage level that occurs at the first capacitor. | 03-31-2011 |
