Abstract
A buffer arrangement uses separate amplifiers for handling for positive going signal transitions and for negative going signal transitions respectively. A comparator detects the direction of transition and a switching element connects signal input lines in the appropriate sense to the respective amplifiers based on the output of the comparator. This permits amplifiers optimized for positive or negative going transitions to be used. The output of the amplifiers can be connected across a sampling capacitor
