| Abstract: | An overview is made on sample(track)/hold amplifiers. S/H amplifiers have found wide applications in data acquisition, data distribution and analog signal processing systems and become an integral part of high-speed/high-resolution A/D converters. Emphases are placed on open loop S/H amplifiers, high accuracy S/H amplifiers with closed loop structure ( bipolar ), total difference high-speed track/hold amplifiers (BiCMOS) and very high-speed S/H amplifiers (GaAs). Also,some terminologies will be introduced,and the development of the device and its applications will be dealt with in a companion paper. |
