Abstract
Generators are provided for supplying reference signals that are especially suited to signal conditioning systems such as analog-to-digital converters. They generate reference signals with low output impedances that reduce spurious signals and shorten recovery times. Filters are included to decouple reference structures and thereby reduce noise signals, reduce ringing and dampen resonant circuits that may be formed with the inductance of bond wires and various parasitic chip capacitances. The generators are configured to provide this high performance with a reduced current consumption.
