Current Feedback Operational Amplifiers: A Tutorial
Bryan L. Hart · International Journal of Electrical Engineering Education · 1995
Current feedback operational amplifiers: a tutorial In a didactic approach, the amplifying properties of an inverter stage using a current feedback operational amplifier (COA) and one using a voltage feedback operational amplifier (VOA) are compared. Then, following a discussion of COA modelling, the frequency and transient responses of a COA non-inverter stage are analysed.
