Optimal design of a CMOS op-amp via geometric programming
TL;DR: A new method for determining component values and transistor dimensions for CMOS operational amplifiers (op-amps) is described, showing in detail how the method can be used to size robust designs, i.e., designs guaranteed to meet the specifications for a variety of process conditions and parameters.
Journal ArticleDOI
OASYS: a framework for analog circuit synthesis
TL;DR: A hierarchically structured framework for analog circuit synthesis is described and mechanisms are described that select from among alternate design styles and translate performance specifications from one level in the hierarchy to the next lower, more concrete level.

Synthesis of high-performance analog circuits in ASTRX/OBLX
TL;DR: A new synthesis strategy that can automate fully the path from an analog circuit topology and performance specifications to a sized circuit schematic and relies on asymptotic waveform evaluation to predict circuit performance and simulated annealing to solve a novel unconstrained optimization formulation of the circuit synthesis problem is presented.

CMOS op-amp sizing using a geometric programming formulation
Pradip Mandal,V. Visvanathan +1 more
TL;DR: Numerical experiments show that the solutions to the sequence of convex programs converge to the same design point for widely varying initial guesses, suggesting that the approach is capable of determining the globally optimal solution to the CMOS op-amp circuit sizing problem.
