Emission of Parasitic X Rays of Vacuum-electron Tubes with Glass Housings: Implications for the Evaluation of Occupational Doses.
Pöttgen H, Schirmer A, Port M, Nusshardt R. Pöttgen H, et al. Radiat Res. 2024 Mar 13. doi: 10.1667/RADE-23-00161.1. Online ahead of print. Radiat Res. 2024. PMID: 38471522
Despite the large variety of high-voltage semiconductor components for medium and high voltage switching and pulse-forming applications as well as for high-power high-frequency generation, the use of vacuum electron tubes still prevails to a considerable degree. ...This is …

A 340 nW/Channel 110 dB PSRR Neural Recording Analog Front-End Using Replica-Biasing LNA, Level-Shifter Assisted PGA, and Averaged LFP Servo Loop in 65 nm CMOS.
Lyu L, Ye D, Shi CR. Lyu L, et al. IEEE Trans Biomed Circuits Syst. 2020 Aug;14(4):811-824. doi: 10.1109/TBCAS.2020.2995566. Epub 2020 May 18. IEEE Trans Biomed Circuits Syst. 2020. PMID: 32746334
To maintain a high PSRR performance while using such a low-voltage supply, a replica-biasing scheme is proposed to generate a stable bias current for the input stage of the LNA despite large supply interference. By exploiting the signal characteristics in the tetrode recor …

Maximum Theoretical Efficiency Limit of Photovoltaic Devices: Effect of Band Structure on Excited State Entropy.
Osterloh FE. Osterloh FE. J Phys Chem Lett. 2014 Oct 2;5(19):3354-9. doi: 10.1021/jz501740n. Epub 2014 Sep 17. J Phys Chem Lett. 2014. PMID: 26278444
The Shockley-Queisser analysis provides a theoretical limit for the maximum energy conversion efficiency of single junction photovoltaic cells. But besides the semiconductor bandgap no other semiconductor properties are considered in the analysis. Here, we show that …
