Journal of Low Power Electronics and Applications, 2017 In this paper, an ultra-low power (ULP) 10T static random access memory (SRAM) is presented for Internet of Things (IoT) applications, which operates at sub-threshold voltage. The proposed SRAM has the tendency to operate at low supply voltages with high

Lock-in detection for pulsed electrically detected magnetic resonance [PDF]
, 2011 We show that in pulsed electrically detected magnetic resonance (pEDMR) signal modulation in combination with a lock-in detection scheme can reduce the low-frequency noise level by one order of magnitude and in addition removes the microwave-induced non ...

Noise in a CCD image sensor and the new low-noise read-out method.
The Journal of the Institute of Television Engineers of Japan, 1985 固体撮像素子を放送用の高画質撮像素子として適用するために, 付加ノイズ発生要因・量共に少ないCCD型の低雑音化と今後の高画質化の可能性などについて種々の検討を行った.まず, ランダムノイズと固定パターンノイズ (FPN) を分離して定量的に測定することができる分析評価法を数した.次に, 新開発の積分型相関二重サンプリング法, および遅延差雑音除去法を用いた低雑音化信号読出し回路により, ランダムノイズを暗電流のショットノイズの程度まで低減できることを示し, ノイズ低減効果の解析結果との良い一致も得た.さらに, 暗電流とFPNの温度依存性の測定結果から, FPNの主因が暗電流の画素ごとのむらによることも確かめた.これらの結果, CCD型撮像素子の今後の低雑音化には, 信号電荷読出し部のアンプノイズと,

Statistical analysis of read-back signals in magnetic recording on granular media
AIP Advances, 2020 The comprehensive simulation of magnetic recording, including the write and read-back process, on granular media becomes computationally expensive if the magnetization dynamics of each grain are explicitly computed. In addition, in heat-assisted magnetic
