Abstract
Ready-flag circuitry for differential amplifiers. In some embodiments, a semiconductor device may include an amplifier including two inputs, and a ready-flag circuit operably coupled to the amplifier, the ready-flag circuit configured to monitor two or more internal nodes of the amplifier and to produce a signal indicating whether a voltage or current difference between the two inputs has been minimized. In other embodiments, a method may include monitoring, via a ready-flag circuit, a first and a second internal node of a differential amplifier, wherein the differential amplifier is part of a bandgap voltage reference circuit and producing, via the ready-flag circuit, a signal indicating whether an output of the bandgap voltage reference circuit has reached a nominal value.
