At ISSCC 2025, Hendrik Siemßen, PhD student at IMS, presented an innovative 3-in-1 multi-mode amplifier. The microchip he developed achieves high precision without additional trimming. With a logarithmic conformity error of only 0.75% across the entire temperature range from -25 to 200 °C, this advancement sets new standards for applications in extreme environments.
The development of renewable energy sources, such as geothermal energy, places high demands on integrated electronics, which must reliably operate under harsh and noisy conditions at temperatures of up to 200 °C. Leveraging IMS’s expertise in power management, switched-capacitor stages are used to ensure a constant gain, even under extreme temperature conditions.
IMS congratulates Hendrik Siemßen on this outstanding achievement! A special thanks also goes to our industry partner, Baker Hughes, for the excellent collaboration. Hendrik Siemßen is pursuing his PhD at IMS under the supervision of Prof. Bernhard Wicht in the field of Mixed-Signal Circuits (MX).
