TSTE85 Low Power Electronics

Given in ht2

---

Aim

In the course we study the design of communication systems with low power consumption. Methods and tools on all abstraction levels from system and algorithm levels down to circuits are considered. A small project on power estimation and optimization is included.

Prerequisites

Basic course in digital circuits.

Organisation

The course consists of lectures, exercises and project work.

Contents

Power dissipation in CMOS circuits. Physical bounds on low power. Switch activity and switched capacitance. Power estimation on different abstraction levels. Methods and tools for power estimation. Strategies for power optimization. Influence of supply voltage scaling and threshold voltage scaling on delay and power consumption. Multiple threshold voltage techniques. Delay balancing to minimize glitches. Synthesis of state machines. Clock distribution. Layout optimization. Design of CMOS and BiCMOS circuits for low supply voltages. Energy recovery in CMOS circuits. Power management: gating the clock, power down, and asynchronism. Algorithms for low power and algorithm transformations on different abstraction levels and data dependency. Architectures for low power. Arithmetics for low power. System partitioning.
