Temperature-compensated CMOS current reference circuit for ultralow-power subthreshold LSIs
نویسندگان
چکیده
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% in a wide temperature range of −20 to 100◦C.

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...

A low-power temperature-sensing oscillator was developed using a 0.35m standard CMOS process. This oscillator generates a clock pulse whose frequency is proportional to absolute temperature (PTAT frequency). It consists of a PTAT current generator controlled with an external reference clock and a frequency-locked loop biased with an external reference voltage. The PTAT current generator makes u...
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...

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...

A low-power CMOS voltage reference was developed using a 0.35 m standard CMOS process technology. The device consists of MOSFET circuits operated in the subthreshold region and uses no resistors. It generates two voltages having opposite temperature coefficients and adds them to produce an output voltage with a near-zero temperature coefficient. The resulting voltage is equal to the extrapolate...
