Built-in Self-test Circuit for Voltage Controlled Oscillator |
| 摘要 |
A device comprises a radio frequency peak detector configured to receive an ac signal from a voltage controlled oscillator and generate a dc value proportional to the ac signal at an output of the radio frequency peak detector and a feedback control unit coupled between an output of the radio frequency peak detector and an input of the voltage controlled oscillator. |
