The electronics industry is always looking for faster and more efficient designs, and one crucial step in that pursuit is the proposal of design models with improved characteristics and amplification. Each amplifier is capable of achieving the maximum output magnitude by amplifying the input signal. To achieve a low power supply and high speed, the authors designed both inverting and non-inverting topologies for voltage feedback amplifiers (VFOA) and current feedback amplifiers (CFOA). All the designed circuits were tested based on various electrical parameters. Comparing VFOA with CFOA, the former displayed 2.50 mW, 1.816e4 gain, and 1.342kΩoutput resistance, whereas the latter displayed 1.50 mW, 2.7e4 gain, and 15.42kΩ output resistance. This article also examined the impact of output voltage swing and the effect of the derivative of output voltage on different gains for designed CFOA circuits.
