Bipolar time-to-digital converter

摘要

Representative implementations of devices and techniques provide bipolar time-to-digital conversion. For example, either a positive time duration or a negative time duration may be converted to a digital representation by a linear time-to-digital converter (TDC). A set of logic functions may be applied to the input of the TDC to provide start and/or stop signals for the TDC. Further, a correction component may be applied to an input or an output of the TDC to compensate for a delay offset of the TDC.

1. An apparatus, comprising:
a linear time-to-digital converter (TDC) arranged to output a duration value based on receiving a start signal and a stop signal, the apparatus arranged to output a digital value representative of a duration of a time interval and a polarity of the time interval, based on the duration value, the time interval comprising a positive time interval or a negative time interval; and an input component arranged to output the start signal and the stop signal based on receiving a first input and a second input, the first input representative of one of a beginning point or an ending point of the time interval and the second input representative of the other of the beginning point or the ending point of the time interval.
