Hold-Up Capacitor: Value Calculations & Uses

NettetIn sample and hold type A/D converters, the analog input has a switch (typically a FET switch in CMOS) which is opened for a short duration to capture the analog input voltage onto an on-chip capacitor. Conversion is typically star ted after the sampling s witch is closed. Track and Hold Nettetcharge holding capacitor that is disconnected from the analog input pin just before the A/D conversion begins. The holding capacitor must be given sufficient time to charge to its final value, or errors will be introduced into the conversion. The acquisition time that must be allowed is a function of the holding capacitor value,
