Wideband DC-coupled amp/schmidt

AN ALL MONOLITHIC, dc to >I GI*, amplifier/Schmidt trigger with 8 mV rms input sensitivity has been designed using a junction-isolated 5 GHz fT process in spite of the inherent high capacitances. Included on a 1.39 x 1.59 mm chip are electronic gain control, 180’ phase switching, ECL line driver output, all biasing circuits and a one-shot LED driver. A functional block diagram is shown in Figure 1.
