A Design of Sigma-Delta ADC Using OTA
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 5
Abstract
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 ADC. This paper presents a new design of two stages OTA. The design incorporates Sleep insertion technique and leakage feedback current approach for improving design parameters such as gain, and power as compared to earlier work. The design is simulated in 0.18ยตm CMOS technology with supply voltage 1.8V.
