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 minimize the variation from both the charging time and the device characteristics and maximize the range of the input voltage. In the source-follower-type analogue buffer, during a compensation period, a voltage drop is stored in a proposed storage capacitor, and during a data-input period, the output voltage is compensated by the voltage stored in the storage capacitor.
