The fully differential amplifier (FDA) has emerged as a very popular last-stage interface to differential-input analog-to-digital converters (ADCs) spanning the range from 24-bit delta-sigma, 18- to ...
JFETs (junction field-effect transistors) can make low-noise high-impedance amplifiers that are better than any other technology. Like all things analog, they are not the best for everything, but you ...
Figure 1 shows a benign means of interfacing a low-level, wideband differential signal to an analog-to-digital converter (ADC). The FET input stage (AD8066) draws only 6 pA of input bias current and ...
