Abstract: A source-follower-type analogue buffer with an active load, a new compensating operation and a display with the source-follower-type analogue buffers are developed to reduce an error voltage which is the difference between an input voltage and an output voltage of the analogue buffer. The source-follower type analogue buffer can also minimize the variation from both the charging time and the device characteristics and maximize the range of the input voltage.

Abstract: Systems for displaying images. The system comprises a digital-to-analog converter, in which a first conversion stage selects first and second voltages of a plurality of reference voltages according to m most significant bits of a k bit input signal; and a second conversion stage converting n least significant bits of the k bit input signal to a voltage between the first and second voltages. In the second conversion stage, according to first and second bits of the least significant bits, a first switching capacitor unit charges a first capacitor during a first period and then the second switching capacitor unit performs a first charge sharing between the first capacitor and a second capacitor, and the first switching capacitor unit charges the first capacitor again and then the second switching capacitor unit performs a second charge sharing between the first capacitor and the second capacitor.
