?-? modulator can be used for synchronous VFC (SVFC). The synchronous behaviour is good in many applications, but the output of SVFC is not a pure tone like a conventional VFC, but it contains components harmonically related to the clock frequency. The new SVFC (NSVFC) is described. This NSVFC works similarly as conventional SVFC but it has a pure tone on output.
