Therefore, the ΔΣ modulator (DSM) in these devices must have low power consumption. Since biological signals are low-frequency signals, an OTA with a low transconductance Gm is necessary for the Gm-C integrator in the modulator. Therefore, an OTA with a low Gm was proposed, but it consumes a lot of power because it uses two amplifiers. One of the ways to reduce the power consumption of the OTA is to drive it with a low supply voltage. However, the operation of the proposed OTA at low supply voltages leads to a decrease in the input voltage range. In order to solve this problem, we propose a OTA with improved voltage range even under low supply voltage by bulk input. We also propose a low-power consumption DSM that can be operated under low voltage power supplies by using the proposed OTA.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","bibliographic_titles":[{"bibliographic_title":"研究報告システムとLSIの設計技術（SLDM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2024-11-05","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2024-SLDM-207"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":240488,"updated":"2025-01-19T07:57:50.567793+00:00","links":{}}
