Voltage Feedback versus Current Feedback Operational Amplifiers APPLICATION NOTE
Current Feedback (CFB) operational amplifiers have been around for more than 30 years. They were designed for extreme high-speed performance, which Voltage Feedback (VFB) amplifiers could not accomplish at that time. The VFB amplifiers have caught up and sometimes with strikingly better performance than the CFB counterparts. However, CFB amplifiers have one major advantage over VFBs, they maintain their bandwidth over a wide range of signal gain. VFB amplifiers are gain-bandwidth dependent, meaning their bandwidth decreases with increasing signal gain. CFB amplifiers are commonly used in high-speed applications while VFB amplifiers are preferably used in precision applications.
