    Abstract: There is disclosed herein current-mode circuitry for measuring a timing difference between first and second signals, the circuitry comprising: a tail node configured during a measurement operation to receive a current pulse in dependence upon the first signal; first and second nodes conductively connectable to said tail node along respective first and second paths; and steering circuitry configured during the measurement operation to control such connections between the tail node and the first and second nodes based on the second signal to steer the current pulse so that a first portion of the current pulse passes along the first path and a second portion of the current pulse passes along the second path in dependence upon the timing difference between said first and second signals; and a signal output unit configured to output a measurement-result signal indicating a measure of said timing difference based upon one or both of the first and second portions.
