A fully on-die, digitally controlled, 500MHz switching, 250mA rated output buck Voltage Regulator (VR) implemented in 22nm Tri-Gate CMOS is presented. The silicon measured a peak efficiency of 68% and consumed an area of 0.6mm 2 (without output decoupling) with a power density of about 410 mW/mm 2. The paper also demonstrates a controller bandwidth of(More)
