A High-Temperature Folded-Cascode Operational Transconductance Amplifier in 0.8-μm BCD-on-SOI

The rapid growth of the hybrid electric vehicles (HEVs) has been driving the demand of high temperature automotive electronics target for the engine compartment, power train, and brakes where the ambient temperature normally exceeds 150°C. An operational transconductance amplifier (OTA) is an essential building block of various analog circuits such as data converters, instrumentation systems, l...

An Operational Amplifier with Recycling Folded Cascode Topology and Adaptive Biaisng

This paper presents a highly adaptive operational amplifier with high gain, high bandwidth, high speed and low power consumption. By adopting the recycling folded cascode topology along with an adaptivebiasing circuit, this design achieves high performance in terms of gain-bandwidth product (GBW) and slew rate (SR). This single stage op-amp has been designed in 0.18μm technology with a power su...

First Order Sigma Delta Modulator Design using Floating Gate Folded Cascode Operational Amplifier

Power consumption is the major issue in VLSI design. In this paper an efficient low power first order sigma delta modulator is designed for oversampled ADC using floating gate folded cascode operational amplifier, in 0.35 μm Technology. Floating gate MOSFET have low power Dissipation hence it is an attractive solution in design of data converters, low voltage op -amp with rail-to-rail input and...

Low Power Folded Cascode Cmos Operational Amplifier with Common Mode Feedback for Pipeline Adc

This work proposed a low power and high gain folded cascode CMOS operational amplifier with a common mode feedback (CMFB) for Pipeline ADC. The proposed design is implemented in 0.13-μm Silterra CMOS technology. The folded cascode topology has been used for obtaining a high gain and low power consumption. Meanwhile, the CMFB is modified circuit to be a double detection to stabilize the output o...
