(1 of 2)(+) Video applications require a widebandwidth and high speed operational amplifier. The operationalamplifier can be used to drive the LCD backplane (VCOM) or thegamma-correction divider string. However, conventionaloperational amplifiers are inappropriate for video applications

owing to their insufficient speed and narrow bandwidth. Therefore, this work describes a novel high-speed operationalamplifier for video applications. Operating range of the amplifiercan be extended to rail-to-rail supply, thus maximizing systemflexibility. The architecture for a high-speed operationalamplifier is developed that incorporates rail-to-rail circuitry to

satisfy system adaptability. Close loop and open loopfrequencies are then simulated given concerns over frequencyresponse stability. Next, transient responses for small and largesignals for various supplies are simulated for high speed voltagelevel switches.

(2 of 2) Simulation results indicate that theproposed operational amplifier satisfies function-relatedrequests and performs adequately in video applications. Importantly, the proposed operationalamplif ier increases the operating speed in video

applications given its bandwidth of 180 MHz and a slewrate of 220 V/us. Additionally, rail-to-rail operating rangeincreases system flexibility towards various operatingvoltages.

(1 of 2) (+) Given the heavy emphasison time product delivery to the market within the electronicsindustry, project leaders must have sufficient information onproduct development status to resolve problems timely andallocate resources efficiently. However, as a complete

product development cycle includes at least eight criticalsteps and the collaboration of functional departments, agap in the workflow incurs serious project delays andadditional overhead costs. Therefore, this workpresents an efficient customized project management

system to prevent problems and shorten productdevelopment cycle time.

(2 of 2)An eight-step work flow diagram is designed as level-oneactivities to illustrate the working relationship betweendepartments. The subset of each diagram is then defined aslevel-two activities to demonstrate the project sequence withineach department. Next, work time spent per employee is

determined to establish an acceptable time of completion ofeach activity. Additionally, the Gantt chart is drawn to display theproject flow, allocation of human resources and the estimatedproject schedule. Simulation results indicatethat the proposed project management system facilitatessynergy among multidisciplinary field engineers and reduce

product development time by 30%. Inaddition to enabling project leaders to eliminate inefficientcommunication by monitoring status on-line, the proposedmanagement system increases competitiveness by reducingoverhead costs and accelerating product delivery to the market.
