摘要: A Quad Flat Pack (QFP) device includes a semiconductor die attached to a flag of a lead frame. Bonding pads of the die are electrically connected to inner and outer rows of leads of the lead frame with bond wires. The die, die flag, bond wires and portions of the inner and outer leads are covered with a mold compound, which defines a package body. The outer leads are similar to the gull-wing leads of a conventional QFP device while the inner leads form contact points at a bottom surface of the package body. A cut is performed on an inner side of the inner leads to separate the inner leads from the die pad.

摘要: An adaptive phase-lead compensation (zero) circuit is disclosed that can be added to a circuit (e.g., a CMOS-based LDO) to ease the compensation and increase the phase margin of the circuit. By using the disclosed adaptive phase-lead compensation circuit, an adjustable resistance can be connected to any nodes in the compensated circuit rather than just to the voltage source (VDD) or ground (GND), allowing the Miller Effect to be used via a Miller capacitor.
