Abstract
Apparatus and methods for providing regulated voltages are disclosed. Using a single voltage regulator, a plurality of regulated voltages can be generated with a voltage distribution function. These regulated voltages can be used in a variety of applications, for example, as a bias voltage for a power amplifier. In addition, the distributed regulated voltages can implement a variety of functions, such as selectively enabling or disabling power amplifiers.
Claims19
An apparatus comprising:
- a voltage regulator configured to receive a reference voltage, a feedback signal, and a power supply voltage, and to generate based at least in part on the received voltages a regulated voltage;
- and
- a voltage distribution circuit configured to receive the regulated voltage from the voltage regulator and to generate a plurality of regulated voltages voltage in response to one or more distribution 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
- generating a plurality of regulated voltages from the reference voltage using a voltage distribution circuit.
An apparatus comprising:
- means for generating a regulated voltage based on a reference voltage, a feedback signal, and a power supply voltage;
- and
- means for generating a plurality of regulated voltages and the feedback signal based on the regulated voltage.
A computer-readable storage medium comprising instructions that when executed perform a method of:
- receiving a reference voltage and a power supply voltage;
- generating a regulated voltage based at least in part on the reference voltage, the power supply voltage, and a feedback loop that includes at least a portion of a voltage distribution circuit;
- and
- generating a plurality of regulated voltages from the reference voltage using the voltage distribution circuit.
