Compensated gain control device

A compensated gain control device comprising:

• a first comparator including a high voltage input terminal, a low voltage input terminal, a ramp input terminal, and an output terminal,
• a voltage divider including a high voltage terminal and a low voltage terminal coupled to said high voltage input terminal and said low voltage input terminal of said first comparator respectively for supplying different voltage inputs to said high voltage input terminal and said low voltage input terminal of said first comparator respectively,
• a ramp generating device coupled to said ramp input terminal and said output terminal of said first comparator for generating increasing ramp signals and decreasing ramp signals, and
• a second comparator coupled to said ramp generating device for receiving said increasing ramp signals and said decreasing ramp signals from said ramp generating device and for generating compensating pulse signals,
• a coupling capacitor coupled to an output of said second comparator, and
• a load coupled to said coupling capacitor and ground.
