Abstract
A comparator cell for analog-to-digital flash converters is provided that reduces power dissipation and peak voltage drop across a load while improving accuracy. An even number of level sensors are coupled to receive an analog input signal and provide a first and a second current. Each level sensor is biased by a different reference voltage. Means for receiving the first and second current and providing an output is coupled between the level sensors and a pair of load resistors. The load resistors are manufactured in a predetermined resistance ratio depending on the number of level sensors.
