Video preamplifier with fast blanking and halftone capability on a single integrated circuit chip

摘要: A method and circuit (30) for providing drive signals that have a half-tone fast blanking capability to video display (20) has preamplifier (31) integrated on semiconductor substrate (35) receiving an input signal (14) producing output (17) the (20). The may plurality of channels (31', 31") corresponding each color be processed. halftone control (21), also receives (60) connected reduce produced by (31). (22) (80) is substantially turn off constructed with bipolar transistors circuits are MOS transistors, example LinBiCMOS manufacturing process. include amplification stages, (40, 43-45, 48, 50) wherein (21) level prior last stage (50) enable low operations.
