Keywords: Analogue circuits; high-speed amplifiers; operational amplifiers; CFOA; stability analysis; Bode plots; frequency response; analogue simulation

Abstract: In this paper the frequency stability of small-signal high-speed amplifier circuits using Bode criterion is analysed theoretically. In particular, the inverting and non-inverting amplifiers employing current-feedback operational amplifiers are under review. Based on the analysis of the operational principle, the equations for complex transfer functions of both circuits and formulas for the related electrical parameters are obtained. Moreover, using these formulas recommendations for a stable operation are given. As well, design procedure of the amplifiers with resistive and capacitive load is suggested. The efficiency of the proposed procedure and recommendations are verified by simulation modelling and experimental testing of sample electronic circuits.
