Abstract :
An optimized compensation strategy for two-stage transconductance operational amplifiers adopting Miller compensation is presented. The compensation takes advantage of the finite output conductance of the buffer which is used to avoid the right half-plane zero. The proposed strategy allows compensation for the second pole due to the load capacitance to be reached, thus providing better frequency performance
