A New Approach Ultra Low Voltage CMOS Logic Circuits Analysis

چکیده
The operation of digital circuits from power supply voltage of the order of 200mv or less imposes that, in general MOSFETs biased in the sub threshold regime, characterized by the exponential relation between the control voltages and the current. In this paper we analyze some of the basic building blocks of digital circuits operating in the sub threshold region. We analyze the basic CMOS inverter as regards the voltage transfer characteristics, dynamic behavior, and power dissipation. To reduce the dependence of the drain current on the process parameters we show some compensation circuits that adjust the body voltage, with a small silicon area penalty.

Ultra-low power subthreshold current- mode logic utilising PMOS load device
Introduction: Current-mode logic (CML) circuits are widely used in many high-speed and high-performance applications [1]. The differential topology of CML circuits provides high immunity to supply noise and crosstalk, while reduced voltage swing at the output helps to operate the circuit in very high frequencies with low noise generation [1, 2]. These properties make the MOS CML (MCML) topology...

In the ultra low power end of design spectrum when performance is of secondary importance, digital subthreshold logic circuits are more applicable than the regular MOS logic. In this paper, we propose two different subthreshold logic families: 1) variable threshold voltage subthreshold CMOS (VT-Sub-CMOS) and 2) subthreshold dynamic threshold voltage MOS (SubDTMOS) logic. Both these logic famili...

Low power is becoming more and more crucial and in many aspects becoming the number 1 priority when designing new applications. Ultra low voltage CMOS is an approach for producing very low-power CMOS circuits by reducing the supply voltage to several hundred millivolts [1, 2]. To maintain good performance at low supply voltages, the threshold voltages of MOS transistors must also be reduced [3–...
