CEQM = Equivalent capacitance of logic modules in pF  
CEQI = Equivalent capacitance of input buffers in pF  
The power dissipated by a CMOS circuit can be expressed by  
the Equation 1.  
CEQO = Equivalent capacitance of output buffers in pF  
Power (uW) = CEQ * VCC2 * F

CC  
F is the switching frequency in MHz.  
Equivalent capacitance is calculated by measuring ICCactive  
at a specified frequency and voltage for each circuit  
component of interest. Measurements have been made over a

capacitance is frequency independent so that the results may  
be used over a wide range of operating conditions. Equivalent  
capacitance values are shown below.

To determine the switching frequency for a design, you must  
have a detailed understanding of the data input values to the  
circuit. The following guidelines are meant to represent  
worst-case scenarios so that they can be generally used to  
predict the upper limits of power dissipation. These  
guidelines are as follows:  
)
4.1  
4.6  
To calculate the active power dissipated from the complete  
design, the switching frequency of each part of the logic must  
be known. Equation 2 shows a piece-wise linear summation  
over all components.
