Analysis of Operational Transconductance Amplifier using Low Power Techniques
Abstract: The paper presents a low power design of Current Mirror based Operational Transconductance Amplifier. The analysis of operational transconductance amplifier has been carried out using conventional gate-driven and low power techniques realised with quasi-floating gate, bulk-driven and bulk-driven quasi-floating gate transistors. The comparative analysis of performances of the amplifiers designed using the above techniques indicate that the best performance is achieved by bulk-driven quasi-floating gate approach. Using bulk as input, …
