“…[4][5][6] This leads to various research studies that have been conducted to study trends in low-power circuit technologies of CMOS LSIs. [7][8][9] In addition, numerous approaches have been taken in order to suppress and minimize power consumption for digital system implementation. [10][11][12] Since mobile devices are based on batterypowered operation, lowering the supply voltage is an important key technique to support long-time operation.…”

Two new parallel bus coding methods for generating a DC-balanced code with additional bits are proposed to achieve the self-stabilization of the intermediate power level in Stacked-Vdd integrated circuits. They contribute to producing a uniform switching current in parallel inputs and outputs (I/Os). Type I coding minimizes the difference in the number of switchings between the upper and lower CMOS I/Os by 8B/10B coding followed by toggle conversion. Type II coding, in which the multi-value running disparity control feature is integrated into the bus-invert coding, requires only one redundant bit for any wider bus. Their DC-balanced feature and the stability effect of the intermediate power level in the Stacked-Vdd structure were experimentally confirmed from the measurement results obtained from the developed test chips.

This paper describes critical circuit building blocks for emerging sensing applications, particularly those where volume, and therefore power consumption constraints are orders of magnitude below current state of the art. Developments in ultra-low power microprocessors and memories are described, along with sub-nW timekeeping circuits, pW voltage references, and efficient DC-DC voltage conversion circuits at sub-µA current loads. Taken together, these circuit design advances point to a vision of true mm 3 lowcost sensing nodes with hybrid power sources, i.e., scavenged and micro-battery, providing long lifetime and reliable operation.
