The proportional P ...

We present a four-phase integrated buck converter in 45nm SOI technology. The controller uses unlatched pulse-width modulation (PWM) with nonlinear gain to provide both stable small-signal dynamics and fast response (~700ps) to large input and output transients. This fast control approach reduces the required output capacitance by 5X in comparison to a controller with latched PWM at similar ope...
