Please find the answer below The switching power consumption is given by,{:[P_("swiitching ")=(1)/(T)int_(0)^(T)i_(DD)(t)V_(DD)dt.],[=(V_(DD))/(T)int_(0)^(T)i_(DD)(t)dt],[=(V_(DD))/(T)[Tf_(SW)CV_(DD)]],[=CV_(DD)^(2)f_(SW)]:}Suppose the system dock frequency =f.Let f_(8w)=alpha f, where alpha is the acbivity factor.:. The expression for switching power consumption isP_("switching ")=alpha subV_(DD)^(2)f".
