Abstract
A high resolution capture circuit and integrated circuit chip are disclosed and include first and second capture delay lines and an oscillator delay line. The oscillator delay line includes N timing delay elements sequentially coupled in a ring to generate a first clock signal. The first and second capture delay lines each include M capture delay elements sequentially coupled to pass a received signal in a first direction along a first signal path and to pass a clock signal in a second direction opposite to the first direction along a second signal path. The first capture delay line uses the first clock signal and the second capture delay line uses an inverse of the first clock signal. Each capture delay element forms a flip-flop and provides a one-bit output. All delay elements have essentially identical timing and M is equal to either N or to N/2.
