PROJECT TITLE :
High DC gain self-cascode structure of OTA design with bandwidth enhancement
A high DC gain self-cascode structure of operational transconductance amplifier (OTA) design with bandwidth enhancement is proposed. Primarily based on the concept of self-cascode structure, which provides high output resistance and transconductance, the proposed OTA presents a compensation methodology to get higher unity-gain bandwidth. The proposed OTA is compared with previous structures, with the identical size of input/output transistors and compensation capacitance furthermore load capacitance, and simulation results show a DC gain enhancement of >twentypercent and a pair of.4 times unity-gain bandwidth at the identical time, and the performances of the proposed OTA bring a better figure of advantage (FOM).
