Cross coupled differential pair
WebFeb 9, 2015 · In this article, we study applications of the cross-coupled pair (XCP) in analog and RF circuits. The XCP can serve as a negative resistance or a negative impedance converter in small-signal operation, or a regenerative circuit in large-signal operation.
