N2 - This paper presents a wide-dynamic-range high-resolution timedomain converter concept tailored for low-power sensor interfaces. The unique system structure applies different techniques to reduce circuit complexity, power consumption, and noise sensitivity. A multi-cycle concept allows a virtual delay line extension and is applied to achieve high resolution down to 1ns. At the same time, it expands the dynamic range drastically up to 2.35 ms. Moreover, individually tunable delay elements in the range of 1ns to 12 ns allow on-demand flexible operation in a low- or high-resolution mode for smart sensing applications and flexible power control. The concept of this paper is evaluated by a custom-designed FPGA supported PCB. The presented concept is highly suitable for onchip integration.
