This paper discusses the challenges of performing powered-up vector testing of low voltage technologies on In-Circuit testers and the safeguards that are necessary to ensure that test vectors do not violate the increasingly tight specifications of low voltage parts. Topics include why manufacturers are adopting low voltage technologies, what happens when low voltage components are exposed to st...

In this paper a new rail-to-rail pixel readout architecture is proposed to enhance the performance of CMOS image sensor for both low voltage and low power applications. Due to this new readout circuit, the enough input voltage swing under a low supply voltage is achieved and guaranteed for correct successive signal processing. As a consequence, the ability of working under a lower voltage using...

The excessively high temperature in a chip may cause circuit malfunction and performance degradation, and thus should be avoided to improve system reliability. In this paper, a novel oscillation-based onchip thermal sensing architecture for dynamically adjusting supply voltage and clock frequency in System-on-a-Chip (SoC) is proposed. It is shown that the oscillation frequency of a ring oscilla...

In t'his paper we will consider how to select an optimal set of supply voltages and account for level conversion costs when optimizing the schedule of a resource domina.ted data path for minimum average power dissipation. Integer linear program (ILP) and non-linear program (NLP) formulations are presented for a minimum power schedule under latency and throughput constraints. Results are present...

Since the beginning of the digital revolution, the speed of a microprocessor has been governed by Moore's law postulated in 1968 by Intel's co-founder Gorden Moore. Moore suggested that the speed of a microprocessor would double in every 18 months. However, the principle of conservation of energy, more scientific in nature, will eventually dominate and limit the rate at which the speed of a mic...

this paper proposes a low voltage (±0.55v supply voltage) low power (44.65µw) high common mode rejection ratio (cmrr) differential amplifier (d.a.) with rail to rail input common mode range (icmr), constant transconductance (gm) and enhanced frequency performance. its high performance is obtained using a simple negative averaging method so that it cancels out the common mode input signals at th...

|We present a new approach for estimating the maximum instantaneous current through the power supply lines of CMOS VLSI circuits. Our nal goal is to determine the peak currents and voltage drops through power supply lines of real VLSI circuits within a practical time. Our approach is based on the iMax algorithm[1] of estimating the upper bound of the current, and uses an improved timed ATPG-bas...

Operational amplifiers have traditionally been operated using dual power supplies–often +15 volts and -15 volts. However, that is not a requirement. An op-amp will operate with any upper and lower power supply voltage provided the voltage across the amplifier is less than maximum ratings and voltages at the terminals are within the specification range relative to the power supply voltages. This...
