A signal generator includes a data source, a power source, and a modulator. The modulator is configured to modulate a power signal from the power source with a data signal from the data source to generate a modulated power signal. Data values of the data signal correspond to variations in a voltage level of the modulated power signal over time. The modulator is coupled to output the modulated data signal to a one-wire interface.

System and method for communicating over a single-wire transmission line

A reference output device includes a low side selector configured to select a first voltage level as an output signal. The output signal is a reference voltage. The reference output device also includes a high side selector configured to select a second voltage level as the output signal. The reference output device also includes a slew rate control configured to switch the output signal between the first voltage level and the second voltage level at a constant slew rate.

Slew rate control for multiple voltage domains

Embodiments of a linear voltage regulator are described. In one embodiment, the linear voltage regulator includes a PMOS low drop-out (LDO) regulator configured to convert an input voltage to a regulated voltage, a charge pump connected to the PMOS LDO regulator and configured to amplify the regulated voltage into an amplified voltage, and an NMOS LDO regulator connected to the charge pump and configured to convert the amplified voltage into an output voltage. Other embodiments are also described.
