What is Vernier Delay Line TDC Overview about?

This TDC uses a start signal that propagates through a delay chain with a larger unit delay τ1 and a stop signal that propagates through a chain with a smaller unit delay τ2. The difference between the two propagation delays determines the resolution, with the measurement time interval given by ΔT = N · (τ1− τ2) + ε after N stages. The dynamic range is limited to DR = m (τ1− τ2) by the number m of delay cells. The output of each D flip flop in the chains forms a thermometer code that can be converted to a b
