We present the structure of an analog integrated circuit design laboratory to instruct at both, senior undergraduate and entry graduate levels. The teaching material includes: a laboratory manual with analog circuit design theory, pre-laboratory exercises and circuit design specifications; a reference web page with step by step instructions and examples; the use of mathematical tools for automa...

This paper describes an analogue EHW (Evolvable Hardware) chip for Intermediate Frequency (IF) lters, which are widely used in cellular phones. When analogue Integrated Circuits (ICs) and LargeScale Integrated Circuits (LSIs) are manufactured, the values of the analogue circuit components, such as resistors or capacitors, often vary from the precise design speci cations. Analogue LSIs with such...

Analog and mixed-signal integrated circuits are rapidly becoming more complex. In addition to the traditional problems associated with testing ICs, such as limited controllability and observability, analog and mixed-signal test is vulnerable to measurement induced errors. Constraints on measuring analog signals signiicantly increase the complexity and cost of testers for such circuits. In this ...

We describe a synthesis system that takes operating range constraints and inter and intracircuit parametric manufacturing variations into account while designing a sized and biased analog circuit. Previous approaches to computer-aided design for analog circuit synthesis have concentrated on nominal analog circuit design, and subsequent optimization of these circuits for statistical fluctuations...

This paper describes analog/mixed-signal circuit design in the nano CMOS era. Digitally-assisted analog technology is becoming more important, and as an example, our fully digital FPGA implementation of a TDC with self-calibration is shown. Since pure analog circuits are still present and “good” device modeling is required for their designs, device modeling technology for nano CMOS with complic...

ii To my dear wife, Liang iii Acknowledgments First, I would like to thank my advisor Professor Larry Pileggi for all his support and continuous guidance throughout the past five years. He opened up a wide variety of research topics that I can explore during my early years at Carnegie Mellon University (CMU) and helped me find my research path that eventually leads to this dissertation. Second,...

This work presents a technique for the generation of analog sinusoidal signals with high spectral quality and reduced circuitry resources. Two integrated demonstrators are presented to show the feasibility of the approach. The proposed generation technique is based on a modified analog filter that provides a sinusoidal output as the response to a DC input. It has the attributes of digital progr...

This paper presents a physically based model for the metal–oxide–semiconductor (MOS) transistor suitable for analysis and design of analog integrated circuits. Static and dynamic characteristics of the MOS field-effect transistor are accurately described by single-piece functions of two saturation currents in all regions of operation. Simple expressions for the transconductance-to-current ratio...

We propose and analyze the error and timing of solvers consisting of both analog and digital circuitry for sparse linear systems of equations. We obtain high speed, but low precision from the analog circuits. We combine this with low speed, but high precision from the digital circuits. The hybrid circuit should be faster than digital circuits alone. As a preconditioner to standard iterative sol...

Circuit sizing problem in application specific analog integrated circuit design is in most cases limited to setting MOSFET channel widths and lengths. It is usually performed by hand by an experienced human designer. As the circuit sizing is an optimization process by its nature, optimization methods could be used. They always lead to one of the minima of the cost function while eventual other ...
