Since the RC product of an inverter is independent of its size, the relative delay can be found by adding the three relative inverter delays. e. for f1 D f2 D f3 D 3 x. This result is obtained by simply taking the derivatives of the delay with respect to the two independent tapering factors f1 and f2 . As shown in Fig. 16, the non-inverting twostage buffer solution yields the minimum delay in the load range 22 < x < 82.

(a) Without buffer. 3 How to Reduce Delay The relative delay model is very useful in optimization problems because the same calculations are valid for most, if not all, technology nodes. In this section we will consider how to minimize the delay when the load capacitance is much larger than the input capacitance of the driver inverter. The problem is shown in Fig.

Power dissipation in CMOS circuits occurs because of the following components. 1 Dynamic Power Dissipation Dynamic power dissipation is related to the operation of circuit. Each time the capacitor CL gets charged through the PMOS transistor, its voltage rises from 0 to VDD , and a certain amount of energy is drawn from the power supply. A part of this energy is dissipated in the PMOS device, while the remainder is stored on the load capacitor. During the high-to-low transition, this capacitor is discharged, and the stored energy is dissipated in the NMOS transistor [1, 6].
