Voltage regulator for providing a regulated voltage to subcircuits of an RF frequency circuit |
| 摘要 |
A voltage regulator for a plurality of radio frequency subcircuits of a radio frequency circuit. A first transistor configured to receive, based on a comparison between a reference voltage signal and a feedback signal, a bias signal corresponding to a desired regulated voltage for the plurality of radio frequency subcircuits, output the bias signal, and generate the feedback signal according to the bias signal as output from the first transistor. A second transistor configured to receive the bias signal as output from the first transistor and provide, based on the bias signal, the desired regulated voltage to a respective first one of the plurality of radio frequency subcircuits. A third transistor is configured to receive the bias signal as output from the first transistor and provide, based on the bias signal, the desired regulated voltage to a respective second one of the plurality of radio frequency subcircuits. |

1. A voltage regulator for a plurality of radio frequency subcircuits of a radio frequency circuit, the voltage regulator comprising:
a first transistor configured to (i) receive, based on a comparison between a reference voltage signal and a feedback signal, a bias signal corresponding to a desired regulated voltage for the plurality of radio frequency subcircuits, (ii) output the bias signal, and (iii) output the feedback signal according to the bias signal from the first transistor; a second transistor configured to (i) receive the bias signal from the first transistor and (ii) provide, based on the bias signal, the desired regulated voltage to a respective first radio frequency subcircuit of the plurality of radio frequency subcircuits; and a third transistor configured to (i) receive the bias signal as output from the first transistor and (ii) provide, based on the bias signal, the desired regulated voltage to a respective second radio frequency subcircuit of the plurality of radio frequency subcircuits. |
