Abstract: A ranging front end for low power cm-acurate ranging applications, based on an 8-channel Time-to-Digital converter is presented. The implementation, fully digitizing pulses with a pulse rate up to 33 MHz, contains 8 non-strobed comparators attached to an 8-channel, low power, 74 ps resolution, 53 ps single shot precision TDC-array, interconnected through 200 mV low swing bit line signaling. The complete system consumes 4.7 mW in active mode and the integrated TDC is competitive to state-of-the-art sub-100 ps resolution multiple TDC-core integrations in terms of power per core and area. The complete pulse digitization enables implementation of a wide variety of time-of-arrival estimation techniques in the digital back end.
