Temperature-compensated CMOS current reference circuit for ultralow-power subthreshold LSIs
This paper proposes a low-current reference circuit for power-aware LSI applications. The circuit consists of two current generation subcircuits which are based on β-multiplier circuit, one with a positive and the other with a negative temperature coefficient. The variation of the reference current in a sample circuit designed to produce a current of 230 nA can be kept very small within ±1.3% i...
متن کاملPower-supply circuits for ultralow-power subthreshold MOS-LSIs
A low-voltage power supply circuit is developed for micropower CMOS LSI applications, especially for microwatt smart-sensor LSIs. The circuit consists of a switched-capacitor voltage converter and a series regulator. The switched converter lowers battery voltage 1.5–3V to a low voltage of 0.5–0.7V to drive the series regulator, and the series regulator provides LSI logic gates with a power volt...
متن کاملA picopower temperature-compensated, subthreshold CMOS voltage reference
A voltage reference consisting of only two nMOS transistors with different threshold voltages is presented. Measurements performed on 23 samples from a single batch show a mean reference voltage of 275.4mV. The subthreshold conduction and the low number of transistors enable to achieve a mean power consumption of only 40 pW. The minimum supply voltage is 0.45 V, which coincides with the lowest ...
متن کاملOn-chip Power Supply for Subthreshold-Operated CMOS LSIs
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...
متن کاملPaper Title (use style: paper title)
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...
