Existing clone tracking tools have limited support for sharing clone information between developers in a large scale system. Developers are not notified when new clones are introduced by other developers or when existing clones are modified. We propose a client-server architecture that centrally detects and maintains clone information for an entire software system stored in a version control system...
Area-efficient resistor-capacitor DACs (R-C DACs) and low-offset push-pull output buffers for a 10-bit LCD source driver are proposed. Comparing to a 10-bit resistor-string DAC (R-DAC), the 10-bit R-C DAC has a smaller area. A new output buffer with a push-pull function is adopted so that the source driver can drive the pixel with two-dot inversion to save power consumption. To reduce channel to channel...
A new compact rail-to-rail buffer amplifier for active matrix liquid crystal display source driver applications is proposed. Two complementary buffer amplifiers driving a pair of column lines are used to realize a rail-to-rail driver. The compact buffer amplifier has a large driving capability with the function of charge and discharge provided by the current positive-feedback (CPF). The CPF can increase...
The design of a compact low-power highspeed class-AB buffer amplifier for driving the large column line loads of large-size TFT-LCD is presented in this paper. The class-AB buffer amplifier can drive large column line loads up to lOOOpF within 1.28 mus. The proposed class-AB buffer amplifier is implemented with a standard 0.35 mum CMOS 2-poly 4-metal process technology and simulated using HSPICE....
