A TIME-DIGITAL CONVERTER AND AN ELECTRONIC SYSTEM IMPLEMENTING THE CONVERTER

摘要

A time-digital converter (100) comprising: an adjustable delay device (D1; DN) for generating a delayed signal (S1) provided with a delay adjusting input (5), and an arbiter device (FF1) for receiving the delayed signal and a reference signal (So) on corresponding inputs and for supplying an output signal (SD1) to an output (O1) indicative of a relative timing of the signals at its inputs. The converter further comprises: a calibration delay device (Dbm) for supplying the reference signal to the arbiter device, and a calibration filter (F1) connectable to said output (O1) for providing input (5) of the adjustable delay device with a delay adjusting signal (S21) depending on the output signal of the arbiter device.
