Abstract:
1. A radio frequency integrated circuit, comprising: at least one noise source residing on the radio frequency integrated circuit, the noise source being controllable by a digital input signal to the noise source, wherein the digital input signal enables generation of a noise signal by the noise source such that the noise source generates the noise signal in response to receipt of the digital input signal, and wherein the digital input signal is operable in a first state to connect a supply voltage to the noise source enabling generation of the noise signal by the noise source, and in a second state to disconnect the supply voltage from the noise source, thereby preventing generation of the noise signal by the noise source; and a radio frequency circuit residing on the radio frequency integrated circuit and being coupled to the noise source, wherein at least one attribute of the radio frequency circuit is determinable by controlling the noise source via the digital input signal.
