A digital-to-phase converter (DPC) generates a 125MHz clock with phase shift controlled by an 8b digital input. Averaging resistor rings are used for phase interpolation and phase error reduction by averaging. Implemented in a standard 0.35μm CMOS technology, the DPC achieves ±1LSB differential nonlinearity and ±2LSB integral nonlinearity. Power dissipation is 110mW with a 3.3V supply.
