Abstract : Instances may arise where it is important to monitor system calibration for long periods of time. It is frequently inconvenient to recalibrate the measuring system, especially during testing. A sample-and-hold circuit which stores necessary recalibration levels for long periods of time has been designed, built, and evaluated. Depending on the operational amplifier used, the circuit is capable of less than 7 mv/hr voltage drift over the full plus or minus 10v input voltage range. (Author)
