Bridge-stabilized oscillator with feedback control |
| 摘要 |
A bridge-stabilized oscillator with feedback control includes an RF amplifier connected to a first bridge path and a second bridge path. Each first and second bridge path has a variable gain amplifier to receive and modify the respective signals to maintain the resistance of a resistor in the first bridge path, so the resonator in the second bridge path oscillates. A power detector provides a control signal to each of the variable gain amplifiers to maintain the phase of the output with respect to the input and constrain the gain in each of the first and second bridge paths. |

1. An oscillator circuit, comprising:
a bridge-stabilized oscillator having a first bridge path and a second bridge path; a variable gain amplifier in each of the first bridge path and the second bridge path; and a power detector detecting a sum of an output of the first bridge path and an output of the second bridge path and for providing a control signal to each of the variable gain amplifiers in the first bridge path and the second bridge path. |
