Low Power Features of Standard Cell Library<br />

With today's proliferation of low power applications, lowering energy consumption without sacrificing performance has become<br />

a critical concern for designers of power management chips for portable electronics. <strong>UMC</strong> supports its standard cell library with<br />

low power design features, including multiple Vt, clock-gating, level shifter and other features to complement <strong>UMC</strong>’s complete low<br />

power solution.<br />
