Abstract
A radiation-hardened charge pump circuit is provided. The circuit includes a first charge pump having a first charge pump output, a second charge pump having a second charge pump output, a first coincidence detector receiving as inputs the first charge pump output and the second charge pump output and producing as an output a first coincidence signal, and an analog 2:1 multiplexor for selecting either the first charge pump output or the second charge pump output based on the first coincidence signal. In alternative embodiment, the circuit includes at least three charge pumps, at least two coincidence detectors, decision logic, and a correspondingly-sized analog multiplexor.
