CMOS op-amp sizing using a geometric programming formulation
The problem of CMOS op-amp circuit sizing is addressed here. Given a circuit and its performance specifications, the goal is to automatically determine the device sizes in order to meet the given performance specifications while minimizing a cost function, such as a weighted sum of the active area and power dissipation. The approach is based on the observation that the first order behavior of a...
متن کاملGeometric Programming: a Tool for Cmos Op-amp Design
In this paper a new method for determining the component values and transistor dimensions for CMOS operational amplifiers (Op-Amps) is presented. As a wide variety of design objectives and constraints are Posynomial function of the design variables, the Optimization is done by Geometric Programming. As a consequence we can efficiently determine globally optimal trade-offs among competing perfor...
متن کاملOptimal design of a CMOS op-amp via geometric programming
We describe a new method for determining component values and transistor dimensions for CMOS operational amplifiers (op-amps). 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 amplifier design problem can be expressed as a special form of optimization problem called geometric pr...
متن کاملTwo Stage Op - Amp Using Cmos – Areview
Operational Amplifier (op-amp) is a basic building block of many analog and mixed signal systems. Many different types of op-amp are used to achieve various functions, such as DC biasing, high speed amplifying, reduced voltage supply, high gain. To achieve these parameter successfully there are several techniques.The op-amp contains two stages to increase gain and improve slew rate, voltage swi...
