QUIESCENT ENERGY

The last contribution to the energy dissipation is

due to the quiescent supply current and is given

by :

EQUIESCENT = IQUIESCENT • VS • T

TOTAL ENERGY PER CYCLE

ETOT = (EOFF/ON + EON + ECOM + EON/OFF)bridge 1+

+(EOFF/ON + EON + ECOM + EON/OFF)bridge 2+

+ EQUIESCENT

The Total Power Dissipation PDIS is simply :

PDIS = ETOT/T

Tr = Rise time

TON = ON time

Tf = Fall Time

Td = Dead time

T = Period

T = Tr + TON + Tf + Td

7/10
