Digital Circuit Optimization via Geometric Programming
This paper concerns a method for digital circuit optimization based on formulating the problem as a geometric program (GP) or generalized geometric program (GGP), which can be transformed to a convex optimization problem and then very efficiently solved. We start with a basic gate scaling problem, with delay modeled as a simple resistor-capacitor (RC) time constant, and then add various layers ...
متن کاملVLSI Circuit Performance Optimization by Geometric Programming
Delay of VLSI circuit components can be controlled by varying their sizes. In other words, performance of VLSI circuits can be optimized by changing the sizes of the circuit components. In this paper, we define a special type of geometric program called unary geometric program. We show that under the Elmore delay model, several commonly used formulations of the circuit component sizing problem ...
متن کاملDesign of pipeline analog-to-digital converters via geometric programming
In this paper we present a method for the design of analog-todigital converters (ADCs). This method computes the sizes of the different components (transistors, capacitors, etc.) in a predefined ADC topology so that the design specifications are met in the desired process technology. The method is based on formulating the ADC design constraints such as specifications on power, signal-to-noise r...
متن کاملOptimization of Phase-Locked Loop Circuits via Geometric Programming
We describe the global optimization of phaselocked loop (PLL) circuits using geometric programming (GP). Equations for the jitter, frequency range, and power of the PLL are presented in GP form. An array of PLL circuits was automatically generated using this technique in a , CMOS process. Silicon measurements show good agreement with the model. The results include a PLL with a period jitter of ...
متن کاملCMOS Operational Ampli er Design and Optimization via Geometric Programming
| We describe a general method for optimized design of CMOS operational ampli ers. We observe that a wide variety of design objectives and constraints have a special form, i.e., they are posynomial functions of the design variables. As a result, the ampli er design problem can be expressed as a special form of optimization problem called geometric programming, for which very e cient global opti...
