Abstract

A method and a circuit are provided for providing phase or frequency synthesis using sigma-delta modulation bit-stream techniques in which data is encoded utilizing sigma-delta modulation and then digital-to-time conversion (DTC) or digital-to-frequency conversion (DFC). In some embodiments this encoded data stream is further subjected to phase or frequency domain filtering, which in some embodiments is carried out by a higher-order phase-locked loop (PLL).
