Abstract
A comparator circuit with comparing means for comparing first and second voltages, has current source circuitry for providing current to said comparing means, said current source circuitry having an input for receiving a clock signal having first and second states, whereby the comparing means starts to compare the first and second voltages when the clock signal makes a transition from the first state to the second state; and means for determining when said comparing means has completed a comparison of said first and second voltages and for switching off said current source circuitry and hence said comparing means when said comparison has been completed
