MCML (MOS Current Mode Logic) is a method used for the purpose of reducing the delay and power of the circuit. In high speed application this method is used to reduce the power. In this method the sleep transistor is inserted in series with the supply voltage (or) current source to reduce the power. Different power gating techniques are been used to reduce the static power and to improve the speed and efficiency of the circuit. In this paper, the filter can be designed by using MCML logic. The
