The flying adder (FA) architecture is one of the latest developments in the area of on-chip frequency synthesis. It has two operating modes: integer-FA mode and fractional FA mode. In the fractional FA mode, a concept of time-average-frequency is used to synthesize certain frequencies that cannot be easily obtained using traditional methods. The issue of using time-average-frequency to drive digital...
We present a procedure for simultaneous optimization of efficiency-bandwidth product and superfluorescence noise suppression in ultrabroadband high-energy optical parametric chirped pulse amplification. Gain dependence of parameters makes stage-by-stage signal chirp optimization necessary in multi-stage amplification.
