Abstract :
First, new stability conditions for low-power CMOS nested Miller compensated amplifiers are given in this brief. Then, an improved structure, which takes the advantages of a feedforward transconductance stage and a nulling resistor, is introduced. Experimental results prove that the proposed structure improves the frequency response, transient response, and power supply rejection ratio without increasing the power consumption and circuit complexity
