Abstract:
A Time to Digital Converter (TDC) arrangement includes a first delay circuit configured to receive a signal with N phases; a set of phase detectors configured to compare each phase of the signal with a reference signal; a logic circuit configured to receive output signals from the set of phase detectors and detect which phase signal that is the closest signal leading or lagging the reference signal; a first multiplexer configured to receive outputs from the first delay circuit and the logic circuit; a second delay circuit configured to delay the reference signal; a TDC configured to receive output signals from the first multiplexer and the second delay circuit; an adder configured to sum outputs from the logic circuit and the TDC and generate an output signal of the TDC arrangement.
