Simulation and Characterization of Voltage Follower for Class A topology in CMOS

This paper is about two class-A voltage followers like basic voltage follower and super source follower. Both have their own advantages and limitations. Here using ideal current source and then using a current mirror as a source current analysis done for both basic voltage follower and super source follower. After doing that process results are used to compare the performance of the above voltage followers. All analysis was supported by the simulation results. Various topologies of voltage follower like Basic voltage Follower, Super Source Follower are designed in 180nm technology with ±1.8V power supply. These different The analysis are made in terms of gain, bandwidth, offset and Delay using ELDO spice, IC station and Design architect of mentor graphics
