1. A voltage selection module comprising:
- an analog voltage input coupled to an analog voltage source;
a digital based voltage input coupled to a digital based voltage source, the digital based voltage source including a Mobile Industry Processor Interface (MIPI) interface and a digital-to-analog converter (DAC) coupled to the MIPI interface, the MIPI interface configured to provide a digital signal to the DAC; and
a control component coupled to the analog voltage input and the digital based voltage input, the control component configured to select a first voltage from the analog voltage input or a second voltage from the digital based voltage input based on a determination of whether to use the first voltage or the second voltage to provide a reference voltage to a voltage regulator coupled to the control component, the control component further configured to provide the reference voltage to the voltage regulator.

Abstract
Circuits, devices, and method for selecting voltage sources. A voltage selection module may include an analog voltage input. The voltage selection module may also include a digital based voltage input. The voltage selection module further include a control component coupled to the analog voltage input and the digital based voltage input, the control component configured to determine whether to use a first voltage received from the analog voltage input or a second voltage received from the digital based voltage input to generate an output voltage.
