Abstract :
An autonomously bias gated synchronous boost regulator consuming 110nA at 1V is demonstrated in 130nm CMOS. The IC generates regulated 1V output from 30mV input, starts up autonomously (battery-less) at 265mV, and regulates output ranging from 0.78V-3.3V. The peak efficiency is 83% with 10μA and 85% with 10mA load.
