| Abstract: | The ICs made with current-mode and CB technology offer excellent high-frequency performance. Benefiting from the current-feedback architecture, amplifiers achieve a wide band and a high slewing rate, being widely used in amplifying and processing the video and radio signals, and in the high-speed communication systems. With the OPA623 IC as an example,briefly introduces the principle and performance of current-feedback amplifiers and its application in HDTV and CATV transmission. |
