  • HIGH SPEED VOLTAGE FOLLOWING DEVICE FOR ANALOG-TO-DIGITAL CONVERSION SYSTEM
    Publication number: 20100001890
    Abstract: A voltage following device is described, for the driving of a sampling network coupleable to an analog/digital converter, comprising at least one first transistor provided with a first terminal to receive an input signal, and a second terminal to provide an output signal to the sampling network which is representative of the input signal translation of an amount equal to a gate and source voltage of said at least one first transistor. The voltage following device having a driving network of said at least one first transistor to keep said gate and source voltage equal to a shift reference voltage.
