Hi,
For the design of a CML based XOR gate, at low frequency it works fine.
As I increase the frequency ~1GHz, the o/p has a delayed rise time. What parameters do I need to change to get the accurate waveforms?
W/L ratios in the attachment Schematic
Waveform here
Q is the output.
IBM 130nm technology.
Tail current 10uA.
