ELECTRONIC DEVICE, A DIGITAL-TO-ANALOG CONVERTER, AND A METHOD OF USING THE ELECTRONIC DEVICE |
摘要 |
In one embodiment, a D/A converter includes a D/A module and a first differential amplifier. The D/A module converts a digital signal to a first analog signal. The first differential amplifier amplifies the first analog signal from the D/A module to a second analog signal. In another embodiment, an electronic device includes D/A converters and sample-and-hold circuits coupled the D/A converters. The D/A converters may or may not include the D/A modules and differential amplifiers. In still another embodiment, an electronic device includes a first electronic component and a first control signal regulator coupled to the first electronic component. A method of using the electronic device includes determining a first maximum setting for the control signal regulator in order to achieve a first radiation intensity from the first electronic component during a first time period and determining a second maximum setting during a second time period.
