Abstract:Low‐noise and low‐voltage operation is prime requirement of an operational transconductance amplifier for low frequency applications. However, achieving low‐noise operation at low supply voltages is a challenging task in CMOS technology owing to noise‐power and noise‐stability tradeoffs. This article outlines, the design of four differential bias self‐cascode (DBSC) operational transconductance amplifiers (OTAs) working at ±0.7 V. The four design techniques namely gate driven (GD), bulk driven (BD), bulk drive… Show more
