Abstract
A polyphase amplitude detector for detecting the amplitude of a polyphase signal. The polyphase amplitude detector includes means for generating differential pair signals. The differential pair signals are buffered and amplified and then AC coupled to the amplitude detector. The amplitude detector detects the amplitude of each phase of the polyphase signal and generates output signals which are used to control the amplitude of the polyphase signal.
