Abstract :
The author describes an op amp that combines a novel error feedback architecture with a folded-cascode circuit to produce a single gain stage high-speed op amp with DC precision comparable to that of multiple gain stage circuits. The 2210 μm×3170 μm chip was fabricated in a dielectrically isolated 400-MHz complementary bipolar process
