Abstract:
A phase shift amplification and detection system comprising:a phase shift amplifier comprising a first flip flop operated in its metastable region wherein a phase shift in an input signal to said first flip flop generates a resulting phase shift in an output of said first flip flop, and said phase shift amplifier, in orders of magnitude greater than said phase shift in said input signal;a detection circuit for detecting timing delays in said output of said phase shift amplifier, said detection circuit coupled to said phase shift amplifier; anda first clock signal and a second clock signal that are out of phase, wherein said first clock signal is coupled to said phase shift amplifier, said first clock signal is for triggering a transition in said phase shift amplifier and said second clock signal is coupled to said detection circuit, said second clock signal is for trigging a transition in said detection circuit.
