LOW POWER, HIGH SPEED LOGIC CONTROLLER THAT IMPLEMENTS THERMOMETER-TYPE CONTROL LOGIC BY UTILIZING SCAN FLIP-FLOPS AND A GATED CLOCK

The power dissipation, logic complexity and chip area of a thermometer controller are all significantly reduced by utilizing a series of scan flip-flops that are connected together to form a bi-directional shift register, along with a gated clock signal that clocks the series of scan flip-flops.
