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...

Ultralow-voltage, minimum-energy CMOS

minimum-energy CMOS S. Hanson B. Zhai K. Bernstein D. Blaauw A. Bryant L. Chang K. K. Das W. Haensch E. J. Nowak D. M. Sylvester Energy efficiency has become a ubiquitous design requirement for digital circuits. Aggressive supply-voltage scaling has emerged as the most effective way to reduce energy use. In this work, we review circuit behavior at low voltages, specifically in the subthreshold ...

Design of power-efficient adiabatic charging circuit in 0.18μm CMOS technology

In energy supply applications for low-power sensors, there are cases where energy should be transmitted from a low-power battery to an output stage load capacitor. This paper presents an adiabatic charging circuit with a parallel switches approach that connects to a low-power battery and charges the load capacitor using a buck converter which operates in continuous conduction mode (CCM). A gate...

Ultralow-Power SOTB CMOS Technology Operating Down to 0.4 V

Ultralow-voltage (ULV) CMOS will be a core building block of highly energy efficient electronics. Although the operation at the minimum energy point (MEP) is effective for ULP CMOS circuits, its slow operation speed often means that it is not used in many applications. The silicon-on-thin-buried-oxide (SOTB) CMOS is a strong candidate for the ultralow-power (ULP) electronics because of its smal...
