DC Restored 100MHz Current Feedback Video Amplifier
The EL2090 is an extremely versatile video amplifier with an integral on-board DC loop amplifier and sample-hold control circuitry. It is the first complete DC-restored monolithic video amplifier subsystem. It uses a current-feedback video amplifier with a nulling sample and hold The EL2090 is an extremely versatile video amplifier with an integral on-board DC loop amplifier and sample-hold control circuitry. It is the first complete DC-restored monolithic video amplifier subsystem. It uses a current-feedback video amplifier with a nulling sample and hold amplifier specifically designed to stabilize video performance. This application note includes a video signal restorer with some fundamentals about DC restoration. As an application circuit of the EL2090, a x2 gainvideo amplifier is described together with a full evaluation circuit and double sided pc-board artwork. The EL2090 is a high-speed part, and some useful tips on layout have been included.
Although DC restoration is not a new concept, the high slew-rate, fast settling-time and low phase distortion at high frequencies provided by Elantec's family of monolithic current-feedback amplifiers, make CFAs the most attractive video amplifier choice for this application.
