Voltage- and Current-Feedback Op Amp Comparison
Abstract
Compensation techniques for voltage-feedback and current-feedback amplifiers are explored in more depth. Gain/bandwidth are compared, with the limitations of current-feedback amplifier being relaxed compared to the voltage-feedback amplifier. Design equations are compared.
Keywords
Compensation; Current-feedback amplifier; Gain/bandwidth; Voltage-feedback amplifier
10.1. Introduction
The name, operational amplifier, was given to voltage-feedback amplifiers (VFAs) when they were the only op amps in existence. These amplifiers could be programmed with external components to perform various math operations on a signal; thus, they were nicknamed op amps. Current-feedback amplifiers (CFAs) ...
