Abstract :
This paper presents a current insertion transient method which can be applied to determine the system stability. Mathematical consideration is described which shows relationship between phase margin and stability. Total gain 93 dB operational amplifier (Op Amp) is designed in order to apply the proposed transient response. A analog circuit designer may easily investigate his or her own system´s fitness with this method.
