Abstract
A phase interpolator includes phase interpolator circuitries. The phase interpolator circuitries generate an output clock signal from an output node according to phase control bits and clock signals. Phases of the clock signals are different from each other. Each phase circuitry includes phase buffer circuits. Each phase buffer circuit is turned on according a first bit and a second bit of the phase control bits, in order to generate a signal component in the output clock signal according to a corresponding clock signal of the clock signals. Each phase buffer circuit includes a first resistor and a second resistor, and transmits one of a first voltage and a second voltage to the output node according to the corresponding clock signal, in which the first voltage is transmitted to the output node via the first resistor, and the second voltage is transmitted to the output node via the second resistor.
