Delay Lines using Active Elements

[maria98]

Hi

Producing line delay, say 100 ps, is quite lossy with passive elements as line losses are too high. What is the most up-to-date technique to get line delay using active elements?

100 ps is about 16 mm PCB trace. Not particularly lossy. Also lumped LC delay lines can be considered if transmission line lengh becomes too large.

But prerequisites are mostly untold. Delaying anylog or digital signals, intended frequency range?

Analog or digital? impedance ? rise time? amplitude? Pulse or step delay?

With a lossless source and mismatch load (2x) there is a 6 dB gain at the 0.25 wavelength in a perfect lossless transmission delay line of 30 mm. ( semi-rigid coax) or stripline, microstrip over Teflon or ceramic.
