VIDEO_GAIN_BLOCK

Published:2009/7/9 1:41:00 Author:May | From:SeekIC

This configuration utilizes the wide bandwidth and speed of HA-2540, plus the output capability of HA-5033. Stabilization circuitry is avoided by operating HA-2540 at a closed loop gain of 10, while maintaining an overall block gain of unity. However, gain of the block can be varied using the equation:A maxlmum block gam of 3is recommended to prevent signal distortinThis ciruit was tested for differential phase and differential gatn using a Tektronix 520A vector scopeand a Tektronix 146 video signal generator Both differential phase and differential gain were too small tobe measured．
