A new high-resolution time-to-digital converter (TDC) architecture based on MOS-Current-Mode-Logic (MCML) is described. Aiming at high resolution and large dynamic range, the prototype is implemented with 0:13 μm CMOS technology. A time domain resolution of 10:6 ps and a respectively large dynamic range of 100 ns was achieved. A switched MCML active load for variable resolution and dynamic range capability is described.
