Abstract:

Time-to-digital converter (TDC) was developed in application-specific integrated circuits (ASIC) and in recent years it can be implemented purely with FPGA. Once the digitizers are implemented into the FPGA that collects data, system flexibility is significantly increased while the cost is reduced. The applications of FPGA TDC are not limited to the time measurements. With appropriate signal conditioning, the FPGA TDC can be used to digitize signals in analog domain, ranging from regular continuous analog-to-digital converter (ADC) to pulse time and charge measurements. In this presentation, the FPGA TDC schemes will be briefly reviewed and then the primary focus will be on the various examples of applications such as high channel count ADC, small current measurement, pulse time and pulse shape digitization, etc.
