A 42.7Gb/s Optical Receiver With Digital Clock and Data Recovery in 28nm CMOS

open access: yesIEEE Access
This paper presents a broadband optical receiver that employs multiple bandwidth extension techniques in analog front-end (AFE) and has efficient digital clock and data recovery (CDR). The AFE is implemented exclusively with inverter-based stages.

Experimentation and Learning in Business Model Innovation for Sustainability in Incumbent Firms: An Integrative Review

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The pressure on corporations to contribute to sustainable development is increasing. It is widely recognised that the sustainable development goals and deadlines cannot be achieved without the support of incumbent firms. Business model innovation (BMI) is identified as a means for businesses to contribute to sustainable development.

More Than 10 Years on: Does a State‐of‐the‐Art Review and Synthesis Offer New Frameworks to Guide Future Design for Remanufacturing Research?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT There is strong evidence that design for remanufacturing (DfRem) can reduce initial‐design carbon emissions by up to 30%, and that product design can critically affect remanufacturing feasibility, yet academic adoption of DfRem remains limited.

Versatile Digital GHz Phase Lock for External Cavity Diode Lasers

open access: yes, 2009
We present a versatile, inexpensive and simple optical phase lock for applications in atomic physics experiments. Thanks to all-digital phase detection and implementation of beat frequency pre-scaling, the apparatus requires no microwave-range reference ...

Circular Economy Pathways for Airport Climate Change Mitigation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...
