Sigma-Delta Analog-to-Digital converter (ADC), is widely used in portable electronic products. An operational transconductance amplifier (OTA) is one of the most important components of this ADC. This paper reports a new design of low power fully differential OTA. In this design authors have used adaptive biasing technique and DC gain enhancement technique for improving design parameters as compared...
Modern day technology has extended its reach below 20 nm. All kinds of effects are to be seen in MOS devices due to different leakage mechanisms at deep sub-micron levels. These lead to errors in the system. Error tolerance (ET), an emerging concept in the field of VLSI design and test: by easing the restriction on accuracy, can be used to have improvements in speed and power depending on the amount...
