Abstract
Noise test systems, methods, and circuitries are provided for determining a phase error of a first modulator using a second modulator. In one example, an integrated circuit device includes a first modulator configured to modulate a first signal to generate a first modulated signal and a second modulator configured to modulate a second signal to generate a second modulated signal. The first signal and the second signal are based on the same reference signal. The integrated circuit device also includes analysis circuitry configured to determine a phase error of the first modulator based on the first modulated signal and the second modulated signal.
