Abstract

Power Management Units (PMU) are present in most electronic devices today. However, for power and area constrained applications, their design becomes a real challenge, especially when cell-sized autonomous microsystems are targeted. This paper presents an LDO regulator and a voltage reference, which are usually a must in any PMU, for autonomous microsystems fabricated in 65 nm CMOS technology. This PMU has been designed to minimize quiescent power and area, consuming a minimum power of 15.6 nW and occupying only 391 mu m(2), while being able to deliver up to 40 mu A to the load. No significant degradation was observed, as the measured line regulation is 0.173%/V, the temperature coefficient is 128.4 ppm/C-degrees over a very wide temperature range going from 0(degrees)C up to 120(degrees)C, and the PSR at low frequencies is - 67.1 dB.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-25:

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 3 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

    It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

    • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
    • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://oa.upm.es/87821/

    As a result of the publication of the work in the institutional repository, statistical usage data has been obtained that reflects its impact. In terms of dissemination, we can state that, as of
