This paper presents the implementation and measurements of a novel ultra-low power low voltage multi-bit continuous-time sigma-delta (CT-∑Δ) modulator, whose quantizer and feedback DACs operate in the time domain. Instead of the conventional flash quantizer and mismatch corrected multi-bit feedback DACs, a Dual-Slope (DS) quantizer and a Pulse-Width Modulated (PWM) DACs have been adopted in this design. The modulator has been implemented in a standard 0.18μm CMOS technology and features 83dB dynamic-range (DR) for a signal bandwidth of 256Hz. When clocked at 917kHz it consumes 13.3μW from a 1.4V supply.","PeriodicalId":239979,"journal":{"name":"2011 Proceedings of the ESSCIRC (ESSCIRC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128711886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Instead of regulating the AC or DC value of the driving stage in order to maintain a constant primary oscillation, this concept introduces a tunable phase delay into the driving loop. The high voltages of the driving stage can be set to a constant value and do not have to be adjusted. The driving stage can be realized with a set of simple switches applying two fixed voltages to the gyroscope for actuation. This reduces the complexity of the circuitry enormously. Measurements reveal that the frequency is held constant with a sigma of 1Hz and the amplitude regulation is within 0.6% of the defined value.","PeriodicalId":239979,"journal":{"name":"2011 Proceedings of the ESSCIRC (ESSCIRC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130228589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The circuit is able to track the temperature behaviour of the PCM cell current over a temperature range from −40 °C to 80 °C, as is necessary to meet the stringent requirements of multilevel PCM sensing. The proposed scheme is based on an MOS transistor biased in saturation below its zero temperature coefficient (ZTC) point. Only room temperature trimming at wafer sort is required to adjust the value and the temperature dependence of the generated current. Experimental results showed good agreement with experimental data on PCM cells. The error in the programmed temperature coefficient is kept within 10% in any process condition.","PeriodicalId":239979,"journal":{"name":"2011 Proceedings of the ESSCIRC (ESSCIRC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130862004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, three novel techniques are proposed which decrease power consumption even further. High threshold voltage cells reduce leakage and improve stability. Dual swing signalling on the global bitlines reduces energy without compromising robustness. The decoder uses a new type of dynamic gate to increase speed.

First, we summarize some of the insight that allowed early HKMG challenges such as equivalent oxide thickness (EOT) and threshold voltage control to be overcome. Then, we discuss HKMG approaches that enable ultimate EOT scaling, pitch scaling via borderless source/drain contact formation, and the fabrication of multi-gate field-effect transistors.
