These circuits requireless number of transistors as compare to CMOS logic circuits. But they suffer from limitations such as noise tolerance, charge leakage, and power consumption. This noise induce in circuits will affect the performance of dynamic circuits. The our work base on noise of MOSFET in contrast to the conventional method which measures drain current noise of MOSFET and divides it by MOSFET transconductance. Therefore, the need for accurate measurement of I-V characteristics of the MOSFET is eliminated, leading to the better accuracy of the measured noise. To design a noise tolerable circuit using dynamic CMOS logic, a new noise tolerant technique is proposed here and then with the help of software we perform parametric analysis to improve the parameters such as noise margin, worst case delay, delayuncertainty, delay sensitivity from their initial performances. By studying those effects we try to put such parameters which help us to make a noise tolerable circuit.

A generic bilinear hysteretic model is utilized to model the isolation system. The behavior of the pier is assumed to be linear and the foundation system is modeled with frequency-dependent springs and dashpots. Two bridge systems were considered, one representative of short stiff highway overpass systems and another representative of tall flexible multispan highway bridges. Nonlinear time history analyses were employed with two sets of seismic motions; one containing 20 far-field accelerograms and one with 20 near-fault accelerograms. The results from these comprehensive numerical analyses show that soil-structure interaction causes higher isolation system drifts as well as, in many cases, higher pier shears when compared to the fixed-pier bridges ͑no SSI͒.
