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.
