Pages: 153 - 157
In this paper an enhanced fully differential recycling folded cascode operational trans conductance amplifier that achieves higher DC gain with same power and area as that of recycling folded cascode OTA is discussed. Generally, the output impedance of the cascode amplifier depends on the current flowing into the cascode node. Hence, in order to increase the DC gain of the conventional Recycling Folded Cascode OTA the modification is done at the cascode node. The proposed enhanced fully differential RFC OTA is implemented in strong inversion using gm/Id methodology. The design is carried out using UMC180nm technology and studied through simulation. From simulation, we found an increase in DC gain of 9dB, 14dB, and 24dB is achieved without changing the Unity Gain Bandwidth. © 2013 IEEE.
