Abstract
This paper introduces a time to digital converter (TDC) architecture for use with ultra wideband (UWB) radar systems. The basic functionality is interfacing UWB RF-Frontends to standard microcontrollers (μC) without the need of high-speed, high precision analog to digital converters, high performance memories or large high speed logic. The device achieves asynchronous conversion of multiple successive events from time domain to digital domain with picosecond resolution. Primary fields of application include short range, low power UWB Radars like ground penetrating Radars, LIDAR systems or other localization tasks. Secondary fields are ultrasonic measurements and mid range radars. A self-calibration feature is implemented to correct certain nonlinearities and imperfections inherent to the conversion method.
