The proposed technique achieves an average compression ratio of 2.25× on MIT/BIH ECG database. Implemented in 0.35 μm process, the compressor uses 0.565 K gates/channel occupying 0.4 mm2 for 4-channel, and consumes 535 nW/channel at 2.4V for ECG sampled at 512 Hz.

Current-mode sense amplifiers (CSA) are commonly used in eNVM due to their fast sensing against large bitline (BL) load and small cell read currents. However, conventional CSAs cannot achieve fast random read access time (TAC) due to significant summed read-path input offsets (IOS-SUM). This work proposes an asymmetric-voltage-biased CSA (AVB-CSA) to suppress IOS-SUM and enable high-speed sensing without run-time offset-cancellation operations. A 90nm AVB-CSA 1Mb Flash macro with BL-length test-modes was fabricated. The 512-rows AVB-CSA eFlash macro achieves 3.9ns TAC. The test-mode experiments confirmed that AVB-CSA improves 1.48x in TAC for 2048-rows BL-length.

As the input voltage becomes lower, the inductor current is restricted by on-resistance of a driver transistor. Therefore, longer Ton period does not indicate a lager inductor current. In this condition, Ton period for the lowest input voltage operation is determined as the inductor current reaches 85% of its ideal value. The converter should operate in a continuous conduction mode (CCM) to obtain the maximum power from the input. Toff period is set by feed forward control from Ton period to sustain the output voltages. A test chip fabricated by a 190nm CMOS technology operates at the input voltage range from 80mV to 3V with maintaining the two output voltages of 3V and 5V, respectively. This means that the power of 625μW is substantially supplied from the input of 80mV for inner circuits.","PeriodicalId":296544,"journal":{"name":"2013 IEEE Asian Solid-State Circuits Conference (A-SSCC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116654504","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}
