    • This invention involves a bandgap reference circuit in IC. The temperature coefficient of conventional bandgap reference is large and the higher order compensation is difficult to implement. This invention provides an adaptive compensated bandgap reference which solves the problem only using lower order (first order) temperature coefficient compensation. The invention adopts segmental compensation circuit to realize adaptive segmental compensation of bandgap reference with low temperature coefficient. The technical solution includes traditional bandgap voltage reference circuit and adaptive feedback compensation circuit which consists of sample and hold circuit, voltage comparator and control module. This invention controls the bandgap voltage reference through systematical view and it has high process compatibility. This invention can find the best temperature characteristic curve adaptively, the output voltage has low temperature coefficient, meeting the requirement of fabrication process, the implementation is simple with small area. This invention relates to integrated circuits.

    • Systems for providing dual resolution control of display panels are provided. A representative system incorporates two pairs of shift registers, each of the shift registers outputting a shifting signal; two pairs of logic gates; and a switching network coupled among the shifting registers and the logic gates. In a low resolution mode, the switching network causes the shift registers to output shifting signals, with corresponding pulses of the shifting signals of the shift registers of the first pair temporally overlapping with corresponding pulses of the shifting signals of the shift registers of the second pair; and wherein, responsive to the shifting signals, the logic gates output panel control signals, with corresponding pulses of the panel control signals of the logic gates of the first pair not temporally overlapping with corresponding pulses of the panel control signals of the logic gates of the second pair.
