Common mode electronic noise in differential circuits
(2019-07-01)
Article
Open AccessDifferential circuits are assumed to reject common-mode noise yet no parameter is available to describethat rejection as the Common Mode Rejection Ratio (CMRR) applies only to deterministic signals, not torandom noise. We ... -
Design and implementation of a radio wake up reciber
(Universitat Politècnica de Catalunya, 2018-06)
Bachelor thesis
Restricted access - confidentiality agreementWi-Fi is the facto standard protocol for most indoor personal communication devices. Despite this, its usage in IoT solutions is limited, mainly due to the high cost and elevated power consumption of Wi-Fi transceivers. ... -
