CLAMP_AMPLIFIER

Published:2009/7/13 2:11:00 Author:May | From:SeekIC

A clamp amplifier is a limiting or bounding circuit. For input voltages between two levels, VH and VL, the output is proportional to the input. For inputs greater than VH or less than VL (VH or VL × the amplifier gain, AV), irrespective of the input. The threshold voltages, VH and VL, can be fixed or variable. If the amplifier can handle positive and negative input/output voltages, VH and VL can have any positive or negative value within the specified range, as long as VH > VL.
