MODULATION THROUGH DIFFERENTIALLY DELAYED CLOCKS

摘要

A clock modulator can include two configurable delay units and can receive a baseband signal and a clock signal. The two configurable delay units can generate two delayed clock signals, each with different delay amounts. The delay amounts can be based on the baseband signal. The delayed clock signals can be combined to generate a modulated clock signal. A quadrature modulated clock signal can be generated when a first clock modulator receives a first baseband signal and a first clock signal and a second clock modulator receives a second baseband signal and a second clock signal. The first clock signal can be a ninety-degree phase shifted version of the second clock signal. The modulated clock signal from the first clock modulator can be combined with the modulated clock signal from the second clock modulator to generate the quadrature modulated clock signal.

主权项

1. A device comprising:
a first configurable delay unit configured to receive a first clock signal and a first baseband signal and to generate a first delayed clock signal based, at least in part, on the first baseband signal; a second configurable delay unit configured to receive the first clock signal and the first baseband signal and to generate a second delayed clock signal based, at least in part, on the first baseband signal, wherein the second delayed clock signal is different from the first delayed clock signal; and a combiner configured to combine the first delayed clock signal and the second delayed clock signal to generate a modulated clock signal.
