This course covers basic aspects of low-power system design with a focus on portable, battery-powered applications. Based on the understanding that power consumption must be optimized on all design levels (device, circuit, architecture), special attention is paid to the discussion of low-power CMOS circuit blocks (circuit and architecture level). Starting with the digital circuits, students will analyze the dynamic power consumption of the inverter as a first example and will be able to extend the results to more general combinatorial circuits. Students will gain an understanding of analog circuits for voltage conversion (LDO, principle of DC-DC conversion) and switched-capacitor amplifier circuits with respect to functionality and power consumption. They are able to analyze the operation of the circuits at the circuit level. Students will know about related challenges in low-power design (e.g. current mirrors for low voltage operation and circuit noise).

In the accompanying exercise unit, students simulate circuit examples on the computer and compare with the analytical results from the lecture. They gain the foundation to be able to estimate circuit performance using simplified models for hand calculation.


Learning goals

Students understand the essential concepts for power optimization of digital and analog circuits on all design levels (device, circuit, architecture). They are familiar with strategies for low-power circuit design and can apply them. The students become familiar with the operating principles of selected essential integrated circuits (Switched-capacitor amplifiers, digital gates, voltage converters, etc.) and are able to analyze the circuits and determine their key design parameters.
