Analog, Mixed-Signal and Radio Frequency (AMS-RF) Circuits

The activities of this research line focus on the development of design techniques and methodologies, mainly in advanced CMOS technologies, for analogue mixed-signal and radiofrequency circuits, with special emphasis on analogue-digital converters (ADCs) and application specific IPs (intellectual properties) for front-end analogue signal processing applications that require low power consumption, high speed and high resolution. We develop concepts such as robustness against technological variability and environmental conditions, digital calibration, self-correction and self-adjustment. All this in the framework of systems for different applications, and specifically for aerospace and wireless communications applications.
