A Low-Voltage, Low-Power, Two-Stage Amplifier for Switched-Capacitor Applications in 90 nm CMOS Process
Abstract- A novel low-voltage two-stage operational amplifier employing resistive biasing is presented. This amplifier implements neutralization and correction common mode stability in second stage while employs capacitive dc level shifter and coupling between two stages. The structure reduces the power consumption and increases output voltage swing. The compensation is performed by simple mill...
متن کاملLow Power Low Noise CMOS Chopper Amplifier
AbstractChopping is a proficient way to reduce the low frequency offset and 1/f noise in amplifiers. In this paper, a low power low noise CMOS chopper amplifier is presented. It is composed of a two stage amplifier. The first stage’s high output impedance and the equivalent Miller capacitance of the second stage constitute together a low pass filter, which reduces the power consumption. The cir...
متن کاملA Low-Power CMOS Chopper Amplifier for EEG Acquisition Systems
T demand for technologies that help neuroscientists and clinicians to actively observe a large number of neurons in the brain has increased significantly. Currently the biopotential acquisition systems are bulky and not portable that makes it difficult for the on-going diagnostics and causes discomfort to the patient. There is a need to make these systems more compact and to extend their applic...
متن کاملA Low Power Low Noise Two Stage CMOS Operational Amplifier for Biopotential Signal Acquisition System
Monitoring of the biopotential signals in present scenario attract much attention to the researcher due to increasing demand for better quality of life and to enhance interaction between humans and machines. Biopotential signals are relatively weak amplitude and low frequency in nature. Therefore it is required to design a front circuitry that defines quality of signal for processing to the nex...
متن کاملDesign of Two Stage Ultra Low Power CMOS Operational Transconductance Amplifier (OTA) Using 180 nm Technology
This paper deals with well-defined design criteria for ultra low power two stage CMOS operational transconductance amplifiers (OTAs) with simple yet robust implementation in nm dimension. A simple design approach which allows electrical parameters to be univocally related to each circuit element and biasing values for low frequency applications is presented.The operational transconductance ampl...
