The Flip flop circuit is one of the major component in VLSI Low power circuits. In this paper we modified (proposed) a Low power explicit type pulse triggered flip-flop (P-FF) design based on single feed through scheme. The modified design successfully solves the long discharging path problem in conventional flip flop designs to achieve better speed, power performance and avoids unnecessary Q_fdbk transistor. We also design 4-bit Shift Resistor using modified P-FF. The performance has been investigated using 90nm Technology at 1.8 voltage and evaluated by the comparison of the simulation result obtain from TSPICE
