Abstract
A /68/68-hopping accelerator for on-chip power supply circuits is proposed and the effectiveness of the accelerator cir- cuit is experimentally verified. The quick dropper with the linear regulator enables nanosecond-order transient time in on-chip dis- tributed power supply systems. The measured transition time is less than 5 ns with a load circuit equivalent to 25-k logic gates in 0.18- m CMOS. This is to be compared with the case without the accelerator of the order of s and thus the acceleration by two or- ders of magnitude is achieved. Extensions of the basic approach are also discussed including implementation of the quick dropper for a switching DC–DC converter, the control stability improvement, automatic timing generation, and the parasitic element effects of the power lines.
