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.

INTRODUCTION • Sample-and-hold (S/H) is an important analog building block with many applications, including analog-to-digital converters (ADCs) and switched-capacitor filters. A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET (field effect transistor) switch and normally one operational amplifier.
