In contrast to the conventional DC (direct current) scheme, AC polarization breaks the trade-off between input transistor gate size and white noise floor of TIA, a relative low input loading capacitance can be implemented for low noise consideration. Besides, a self-compensation technique combining polarization source and reference in automatic-gain-control (AGC) is put forward. It cancels the 1\/f noise and drift introduced by the polarization source itself, which applies to both DC and AC polarization cases. The experimental result indicates the proposed AC polarization and self-compensation strategy expand the bias-instability of studied SOA from 2.58 \u03bcg to 0.51 \u03bcg with a full scale of \u00b1 30 g, a 155.6 dB dynamic range is realized in this work.<\/jats:p>","DOI":"10.3390\/s20051455","type":"journal-article","created":{"date-parts":[[2020,3,6]],"date-time":"2020-03-06T09:26:41Z","timestamp":1583486801000},"page":"1455","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Expanding Bias-instability of MEMS Silicon Oscillating Accelerometer Utilizing AC Polarization and Self-Compensation"],"prefix":"10.3390","volume":"20","author":[{"given":"Yang","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Department of Instrument Science and Technology, Nanjing University of Science and Technology, Nanjing 210094, Jiangsu, China"}]},{"given":"Guoming","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Department of Instrument Science and Technology, Nanjing University of Science and Technology, Nanjing 210094, Jiangsu, China"}]},{"given":"Qin","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Department of Instrument Science and Technology, Nanjing University of Science and Technology, Nanjing 210094, Jiangsu, China"}]},{"given":"Anping","family":"Qiu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Department of Instrument Science and Technology, Nanjing University of Science and Technology, Nanjing 210094, Jiangsu, China"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Prikhodko, I.P., Bearss, B., Merritt, C., Bergeron, J., and Blackmer, C.
