“…Static calibration methods are represented mainly by trimming, where laser or current blown fuses are used [28]. Dynamic calibration methods include, for example, the chopper stabilization [29], auto-zeroing [30] or digital calibration [31]. The latter method will be more deeply described in Session 4.3.1, where digital calibration of a variable gain amplifier was implemented, with a focus on the input offset voltage compensation.…”

The paper brings an overview of main challenges and design techniques effectively applicable for ultra-low voltage analog integrated circuits in nanoscale technologies. New design challenges linked with a low value of the supply voltage and the process fluctuation in nanotechnologies, such as device models, robustness to process variation, device mismatch and others are discussed firstly. Then, design techniques and approaches to analog integrated circuits towards (ultra) low-voltage systems and applications are described. Finally, examples of basic building blocks of ultra-low voltage analog ICs designed in standard CMOS technology using such design techniques are presented. Finally, the developed circuits are compared to the state-of-the-art solutions in terms of the main parameters and features.
