Abstract:
A time-interleaved sample-and-hold system includes a first sample-and-hold circuit and a second sample-and-hold circuit. The first sample-and-hold circuit and the second sample-and-hold circuit share a common sampling switch. A method of remediating a timing offset between a first sample-and-hold circuit and a second sample-and-hold circuit in a time-interleaved sample-and-hold system includes switching at least one shunt capacitor disposed between two logic gates in a timing circuit to adjust a delay between a timing signal for a common sampling switch electrically coupled to the first and second sample-and-hold circuits and a timing signal for at least one of the sample-and-hold circuits.
