This supply voltage reduction is mainly driven on one hand by the technology constraints to maintain a reasonable electric field within the MOS device to avoid high-field effects and on the other hand by the needs of digital circuits to reduce the dynamic power consumption. Analog circuits unfortunately don\u2019t take any advantage of this voltage down-scaling since almost all their performances are degraded and some basic circuits would even stop operating correctly. We will discuss the main challenges faced when designing analog circuits for ultra-low voltage (ULV) operation. We will first present the fundamental limits set by ULV, together with the technology limitations (such as matching) for analog circuits. We will then have a closer look at the MOS transistor operation with a particular focus on weak inversion, the Gm\/ID characteristic and the inversion coefficient design approach. We then will review several basic building blocks capable of operating at ULV, including both continuous-time and sampled-data circuits. Finally we will investigate the potential of designing RF circuits in ULV taking advantage of ultra-deep submicron processes and give some design examples.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td colspan=\"3\" bgcolor=\"#f2cdd4\" height=\"50\">\n<p align=\"center\"><b>Noise Performance of Elementary Circuit Blocks<br \/>\nBoris Murmann, University of Hawaii<br \/>\n<\/b><\/p>\n<p align=\"justify\">Designing energy-energy efficient analog circuits requires a solid understanding of electronic noise. The material covered in these two modules requires no prerequisite knowledge and looks at shot noise (due to discreteness as charge) as an intuitive baseline for further treatment. After modeling thermal and 1\/f noise at the device level, we analyze its impact on elementary circuits such as common source\/gate\/drain amplifiers as well as switched capacitor structures. We then expand the treatment to feedback circuits with an emphasis on sensor front ends. Lastly, we analyze noise in filters and the noise penalty paid for emulating inductors using active circuits.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td colspan=\"3\" bgcolor=\"#f0f0ef\" height=\"50\">\n<p align=\"center\"><b>Opamp Topologies and Design Fundamentals<br \/>\nBoris Murmann, University of Hawaii<br \/>\n<\/b><\/p>\n<p align=\"justify\">While there exist a myriad of topologies and design tricks for integrated opamps, these two introductory modules intend to untangle the design space with an emphasis on the fundamentals. Covered topics will include: (1) Elementary building blocks operated at low supply voltage and\/or low current: Current mirrors, differential pairs, inverter-based stages, low-voltage cascode configurations; (2) Basic topologies: Telescopic, folded-cascode, and multi-stage; (3) Stability and frequency compensation techniques; (4) fully differential implementation and common-mode feedback.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td colspan=\"3\" bgcolor=\"#f2cdd4\" height=\"50\">\n<p align=\"center\"><b>Low-Power High Efficiency OpAmp Design<br \/>\nKlaas Bult, Analog Design Consult<br \/>\n<\/b><\/p>\n<p align=\"justify\">The goal of this lecture is to find the relationship between circuit performance and power dissipation.

Interaction between these loops makes frequency compensation of such system non-trivial task, unsupported by the general control theory. Every MOS or bipolar transistor is nonlinear, which may cause conditional stability and complicate compensation.<br \/>\nWe will consider system structure design for stability, needed for it elementary circuit cells additional to the textbook techniques, as well as ways to achieve unconditional system stability when component parameters vary, and when load and signal source impedance is not well defined. Examples include LDOs stable with any load capacitance, transconductors with wide (few volts) input voltage range, and multistage operational amplifiers.<\/p>\n<\/td>\n<\/tr>\n<tr>\n<td colspan=\"3\" bgcolor=\"#f0f0ef\" height=\"50\">\n<p align=\"center\"><b>Energy Efficient Voltage References, Biasing in Analog Systems and Current Sources<br \/>\nVadim Ivanov, Texas Instruments<br \/>\n<\/b><\/p>\n<p align=\"justify\">Discussed are principles of the voltage reference generation, primarily of the bandgap voltage references, its error sources and techniques for improving accuracy: circuit techniques for low-noise bandgap generation core, feedback amplifier with chopping offset elimination, output buffer with mOhm output impedance and fast settling on load changes; layout and packaging; testing and application particulars.
