Abstract :
A temperature-stable wide-band current-differencing amplifier resulting from the replacement of the usual operational amplifier structures by integrable current-operated modules is reported. This unity gain network features nearly ideal terminal characteristics (R/SUB IN/<0.3 /spl Omega/, R/SUB OUT/ /spl esdot/ 2 M/spl Omega/) and an external adjustment to maximize the subtraction accuracy, or current gain common mode rejection ratio.
