Abstract: A time-to-digital converter includes: an input for receiving a time-domain input signal; an output for providing a digital output signal; a time register coupled to the input and to a first node; a time quantizer coupled to the time register for providing the digital output signal at the output; and a digital-to-time converter coupled to the output for providing a feed-back signal at the first node.

Abstract: A time register includes: a pair of inputs coupled to a pair of input clocks; a pair of tri-state inverters for producing a pair of level signals; and a pair of outputs coupled to the level signals for producing a pair of output clocks, wherein the tri-state inverters are responsive to a pair of state signals and the pair of input clocks for holding or discharging the level signals.
