Abstract:
A voltage reference source is provided that includes a Brokaw bandgap core comprising a first set of transistors, a second set of transistors coupled to the first set of transistors and serving as load devices to the first set of transistors, and a dynamic element matching circuit coupled to the first and second sets of transistors so as to cancel the offset and noise produced by a selective number of the second set of transistors.
