Design of Low Voltage Low Power CMOS OP-AMP

Operational amplifiers are an integral part of many analog and mixed signal systems. As the demand for mixed mode integrated circuits increases, the design of analog circuits such as operational amplifiers in CMOS technology becomes more critical. This paper presents a two stage CMOS operational amplifier, which operates at ±1.8V power supply using TSMC 0.18um CMOS technology. The OP-AMP design...

Designing 1-V Op Amps Using Standard Digital CMOS Technology

This paper addresses the difficulty of designing 1-V capable analog circuits in standard digital complementary metal–oxide–semiconductor (CMOS) technology. Design techniques for facilitating 1-V operation are discussed and 1-V analog building block circuits are presented. Most of these circuits use the bulk-driving technique to circumvent the metal– oxide–semiconductor field-effect transistor t...

CMOS Technology and Current-feedback Op-Amps

The implementation of currentfeedback op-amps (CFB op-amps) relies on the use of a semiconductor process with complementary device structures for class AB operation of the input and output stages. Thus, CMOS technology is an obvious candidate. However, commercial CFB opamps are all realized in bipolar processes. In this paper we identify some of the problems related to the application of CMOS t...

Design and Performance analysis of Low power CMOS Op-Amp

This paper proposes a low power CMOS operational amplifier which operates at 1.8 V power supply. The unique behavior of the MOS transistors in sub-threshold region not only allows a designer to work at low input bias current but also at low voltage. While operating the device at weak inversion results low power dissipation but dynamic range is degraded. Designing of two-stage Op-Amp is a multi-...

Low-Power Adder Design for Nano-Scale CMOS

A fast low-power 1-bit full adder circuit suitable for nano-scale CMOS implementation is presented. Out of the three modules in a common full-adder circuit, we have replaced one with a new design, and optimized another one, all with the goal to reduce the static power consumption. The design has been simulated and evaluated using the 65 nm PTM models.
