Apparatus for low power high speed integrated clock gating cell
Abstract:
An apparatus for an integrated clock gating cell is provided. The apparatus includes a logic gate that receives an unbuffered enable signal (E), a scan test enable signal (SE), and outputs an inverted enable signal (EN); a first transmission gate that receives E, SE, and EN; a second transmission gate that is connected to the first transmission gate and receives a clock signal (CK) and an enabled and inverted clock signal (ECKN); a first transistor having terminals connected to a power supply voltage (VDD), an output of the logic gate, and the first transmission gate respectively; a second transistor including terminals connected to the first transmission gate and VDD respectively; and a latch including terminals connected to the second transmission gate and the second transistor respectively.
