Introduction to Time
to Digital Converters
Time to Digital Converter (TDC) is a device for converting a signal of sporadic pulses into a digital representation of their time indices. In other words TDC is an electronic
stop watch for measuring quick physical events. In a simple case shown in
figure 1.1 the time interval measured between leading edge of two electrical
pulses applied to the inputs Start
and Stop of TDC. Normally the pulses
are generated from time discriminator used to extract the timing information
from the pulses received from the detectors of some physical events, for
example, light flashes.
I designed different architectures of TDCs on FPGA. I created this blog to share my little knowledge about FPGA programming and VLSI Design. I am working on Time to Digital Converters. If any one need help on these topics contact me through this blog.
