HIGH SPEED SAMPLE AND HOLD Another requirement encountered in sample and hold work is high speed. Although conventional sample and hold cir- cuits can be built for very fast acquisition times, they are dif- ficult and expensive.
If the input waveform is repetitive, the circuit of Figure 5can be employed. Let us understand the operating principle of a S/H Circuit with the help of a simplified circuit diagram. This sample and hold circuit consist of two basic components: Analog Switch; Holding Capacitor; The following image shows the basic S/H Circuit.
This circuit tracks the input analog signal until the sample command is changed to hold command. The AD is a complete monolithic sample-and-hold circuit consisting of a high performance operational amplifier in series with an ultralow leakage analog switch and a FET input inte- File Size: KB.
CIRCUIT TECHNIQUES FOR LOW-VOLTAGE AND HIGH-SPEED A/D CONVERTERS An integral part of an ADC is the front-end sample-and-hold (S/H) circuit. At high signal frequencies its linearity is predominantly determined by the switches utilized.
