<p>Asynchronous and synchronous deglitch controllers controlling switches of sample and hold circuits for deglitching digital to analog converters. Asynchronous and synchronous deglitch controllers detect transitions in the state of the digital input code to trigger or allow a one shot pulse to cause sample and hold circuits to go into hold mode for the period of the one shot pulse. Secondary glitch cancellation circuitry models the environment of the sample and hold circuit to emulate secondary glitch impulse generation. A differential amplifier substantially cancels secondary glitches related to the parasitic charges generated by the switching of the sample and hold circuit.</p> |
