With scaling process generation, power management techniques are more significant. Body bias techniques are useful for the solutions. We propose a high resolution body bias generation circuit which supplies optimal body bias in both the active and standby mode. By using this circuit, the adjustment accuracy of threshold voltage (Vt) in the active mode was improved about 4.1 times of the conventional circuits at 0.6V forward body bias condition. In addition, for standby mode, when 128 kByte SRAM
