Power-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 کاملVariable Supply Voltage for Low Power DSP
The use of dynamically adjustable power supplies as a method to lower power dissipation in DSP is analyzed. Power can be cut substantially without sacrificing performance in applications where the computational workload changes with time. If latency can be tolerated, buffering data and averaging processing rate can yield further power reduction. Continuous variation of the supply voltage can be...
متن کاملA Low-Voltage Low-Power Wide-Range CMOS Variable Gain Amplifier
In this paper, a compact low-power (LP) low-voltage (LV) metal–oxide–semiconductor-only (MOS-only) variable gain amplifier (VGA) is introduced. This amplifier based on complementary MOS (CMOS) transistors operating in strong inversion is composed of a pseudo-exponential current-to-voltage converter, analog multiplier, and output stage. The gain of the amplifier is controlled exponentially by a ...
متن کاملAdaptive Supply Voltage Management for Low Power Logic Circuitry Operating at Subthreshold
With the rise in demand of portable hand held devices and with the rise in application of wireless sensor networks and RFID reduction of total power consumption has become a necessity. To save power we operate the logic circuitry of our devices at sub-threshold. In sub-threshold the drain current is exponentially dependent on the threshold voltage hence the threshold variation causes profound v...
متن کاملA subthreshold current-sensing ΣΔ modulator for low-voltage and low-power sensor interfaces
A continuous-time (CT) ΣΔ modulator for sensing and direct analog-to-digital conversion of nA-range (subthreshold) currents is presented in this work. The presented modulator uses a subthreshold technique based on subthreshold source-coupled logic cells to efficiently convert subthreshold current to digital code without performing current-to-voltage conversion. As a benefit of this technique, t...
