Title: RESISTIVE INTERPOLATION MESH CIRCUIT FOR TIME-TO-DIGITAL CONVERTERS
Abstract:
Resistive interpolation mesh circuits (RIMCs) for time-to-digital converter (TDCs) are disclosed. Ring oscillators (ROs) are arranged and coupled in a two-dimensional parallel configuration, each RO comprising an uneven number of delay elements. The RIMCs may be used in high resolution TDCs with a broad range of applications from positron emission tomography to lifetime, coincidence, synchronous data transfer, distance measurement, 3D imaging systems requiring high resolution timing.
