Abstract
<italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Editor’s notes:</i> This article presents a method for designing bandpass (BP) negative group delay (NGD) active circuits. The circuit topology consists of a distributed BP NGD passive circuit cascaded with a microwave amplifier. The design is validated through simulations and measurements of a prototype implementation. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">—Binoy Ravindran, Virginia Tech</i>
