Abstract

See full text

A frequency linearity measurement circuit configured to measure a frequency linearity of a frequency signal includes: a first measurement circuit having a counter, where the counter is controlled by a gate signal having a gate signal period, where the first measurement circuit is configured to generate a first estimate of an integer number of clock cycles of the frequency signal within a respective gate signal period of the gate signal; a second measurement circuit having a time-to-digital converter (TDC), where the TDC is controlled by the gate signal, and is configured to generate a second estimate of a fractional number of clock cycle of the frequency signal within the respective gate signal period of the gate signal; and a reference measurement circuit configured to generate a third estimate of an expected number of clock cycles within the respective gate signal period of the gate signal.
