Abstract:The standard, junction-isolated power process has been modified by the addition of polycrystalline-film resistors to solve the topological problems encountered in making 90W, 80V, 10A power transistors and connecting them together for a push-pull output. An all-NPN output stage has been developed that holds cross-over distortion to 0.01-percent while driving a 4Ω load, even with the quiescent current below 20 mA. It is stable with all reactive loads and does not have the spurious-oscillation problems observed … Show more
“…A miller capacitor is used to split the poles, which causes the dominant pole to move to a much lower frequency and thus reducing the bandwidth and providing ample stability. This method is featured in the original 741/101 bipolar Op Amps designed by Robert Widlar and was widely implemented henceforth [10]. the RHP zero not only flattens the magnitude response due to the dominant pole but also degrades the phase make it difficult to stabilize the amplifier.…”
