TL;DR: A close matching is seen between the results obtained by proposed and conventional methods with a significant speedup reported.
Abstract: A nonlinear analysis of a DC-DC buck converter is presented in context of its harmonics in a power delivery network (PDN). The closed-form relationships of the harmonic distortions associated with the DC-DC buck converter are derived by Volterra series to estimate the effects in a practical environment using S-parameters. For the validation of the proposed method, the buck converter is designed in a 180 nm LDMOS technology and three test cases are considered by using three different practical PDNs. A close matching is seen between the results obtained by proposed and conventional methods with a significant speedup reported.

TL;DR: In this paper, a generalised indefinite admittance matrix (GIAM) method is proposed to formulate these metrics for active circuits, including the impact of deterministic supply noise on performance parameters.
Abstract: The presence of fluctuations in the power and ground supply rails affect the quality of various performance metrics (gain, phase, impedance, transient response, etc.) of any analog and mixed-signal system. In this paper, a generalised indefinite admittance matrix (GIAM) method is proposed to formulate these metrics for active circuits. The proposed analysis includes the impact of deterministic supply noise on performance parameters. For the purpose of analysis, a common source amplifier, designed in a standard CMOS 180 nm technology, is analysed. The maximum mean percentage error between analytical results and Cadence® Virtuoso® tool simulations for the amplifier is less than 4 % for all the cases.

TL;DR: General techniques to suppress nonlinear behavior such as pre-distortion, linear and nonlinear feedback are explained in detail and illustrated with realistic examples to fill the gap between the theory of nonlinear systems and practical analog integrated circuits.
Abstract: From the Publisher:
Distortion Analysis of Analog Integrated Circuits provides both qualitative and quantitative insight into the nonlinear behavior of analog integrated circuits at low and high frequencies. General techniques to suppress nonlinear behavior such as pre-distortion, linear and nonlinear feedback are explained in detail and illustrated with realistic examples. In this way the book fills the gap between the theory of nonlinear systems and practical analog integrated circuits. Distortion Analysis of Analog Integrated Circuits is essential reading for practicing analog and mixed-signal design engineers and researchers in the field. It is also suitable as a text for an advanced course on the subject.

TL;DR: A new design methodology to analyzethe on-chip power supply noise for high-performance microprocessors based on an integrated package-level and chip-level power bus model, and a simulated switching circuit model for each functional block offers the most complete and accurate analysis of Vdd distribution.
Abstract: This paper describes a new design methodology to analyzethe on-chip power supply noise for high-performance microprocessors.Based on an integrated package-level andchip-level power bus model, and a simulated switching circuitmodel for each functional block, this methodology offersthe most complete and accurate analysis of Vdd distributionfor the entire chip. The analysis results not only providedesigners with the inductive ΔI noise and the resistive IRdrop data at the same time, but also allow designers to easilyidentify the hot spots on the chip and ΔV across the chip.Global and local optimization such as buffer sizing, powerbus sizing, and on-chip decoupling capacitor placement canthen be conducted to maximize the circuit performance andminimize the noise.
