Abstract
A low noise analog sampling circuit that includes a transistor connected to a first feedback loop and to a second feedback loop. During a second operational phase the second feedback loop provides the transistor a feedback signal that is responsive to an amplified error signal; wherein the error signal represents a difference between (i) a sampled signal representative of a state of the transistor short period before a first feedback loop was opened and (ii) a signal representative of a current state of the transistor; wherein at an end of the second operational phase the second feedback loop is opened and introduces a second noise that is attenuated by multiple capacitors.
