On-chip Power Supply for Subthreshold-Operated CMOS LSIs
نویسندگان
چکیده
An on-chip voltage supply regulator for subthreshold-operated CMOS logic LSIs is proposed. The regulator transforms lithium battery voltage 3 V to low supply voltage 0.4-0.5 V for subthreshold-operated CMOS logic LSIs. It monitors the gate delay in the LSI and produces an appropriate supply voltage such that the delay is equal to a value determined by a built-in capacitor-resistor reference. We designed the regulator circuit, using 0.18-!m CMOS parameters, and confirmed its operation with SPICE simulation. Key-Words: CMOS, LSI, subthreshold, on-chip, power supply, switching regulator, switched capacitor

Fig. 1. Schematic of the proposed current reference circuit. Intelligent network systems for the future will require a great number of smart sensor LSIs that measure various physical data in surroundings. These LSIs have to operate with a low power, tens of microwatts or less, because they will probably be placed in non-ideal environments where energy for operation cannot be obtained sufficient...
