چکیده
Reducing Power dissipation is one of the crucial problems in today’s scenario. So this dissipation has become a bottleneck in the design of high speed synchronous systems which are operating at high frequency. Clock signals have been a great source of Power. Design can be made on the basis of Clock gating approach to reduce the consumption of clock’s signal switching power which is the foremost component for the utilisation of the power. The idea of clock gating is to shut down the clock of any component when it is not accessed. Clock gating avoids the redundant switching of clock signal. This Paper presents the design of clock gating technique based sequential circuit; D flip flop, Linear Feedback Shift Register , UART and estimation of Power with or without clock gating. Power analysis is carried out using XILINX X Power Analyser.
