Abstract
We present a simple electronic circuit which provides negative group delays for band-limited baseband pulses. It is shown that large time advancement comparable to the pulsewidth can be achieved with appropriate cascading of negative-delay circuits but eventually the out-of-band gain limits the number of cascading. The relations to superluminality and causality are also discussed.Keywords
