High-frequency and Mixed-signal Integrated Chips
for Information-Systems

The Chair for Circuit Design and Network Theory (CCN)
performs research regarding the design and modelling
of integrated circuits in CMOS, BiCMOS, III/V, organic
and thin-film technologies.

The focus of the research is on the analysis and design
of analogue and mixed-signal circuits from the sub-GHz
range up to millimeter-wave frequencies for future 5/6G
data communications and sensors.

The circuits are e.g. optimized for a high efficiency and a
very low energy consumption. An example of a corres-
ponding research work is shown in the right image. CCN
designed an ultra-low power data transceiver operating
at 433 MHz in 22 nm FDSOI CMOS of GlobalFoundries.
By means of very efficient duty-cycling, use of optimized
body-biasing, etc., it was possible to reduce the DC-power
of the receiver to 500 nW.

This DC-power is so low that the data receiver can be
supplied by organic waste, a piece of fruit such as a
slice of lemon or even natural thermal energy.
