Abstract
Apparatus and methods for providing variable regulated voltages are disclosed. Variable voltage control elements can adjust a regulated voltage provided by a single voltage regulator, thereby providing a variable regulated voltage. The regulated voltage can be used in a variety of applications, for example, as a bias voltage for a power amplifier.
Claims16
An apparatus comprising:
- a voltage regulator configured to receive a reference voltage and a power supply voltage, and to generate a regulated voltage based at least in part on the reference voltage and the power supply voltage;
- and
- a variable voltage circuit configured to receive the regulated voltage from the voltage regulator and to generate at least one variable regulated voltage, the variable voltage distribution circuit including one or more variable voltage control elements configured to selectively control the at least one variable regulated output voltage in response to one or more variable voltage control signals.
A method comprising:
- receiving a reference voltage and a power supply voltage;
- generating a regulated voltage based at least in part on the reference voltage and the power supply voltage;
- and
- controlling the regulated voltage using one or more variable voltage control elements to provide a variable regulated voltages.
