Title:
周波数-電流フィードバックを有する温度安定形発振回路
Document Type and Number:
Japanese Patent JP2013516836
Kind Code:
A
Abstract:
A signal generating circuit and method are disclosed that do not require a phase-locked-loop and a low frequency temperature-stable oscillator. The method may include generating an oscillating output signal responsive to a feedback signal, where the feedback signal controls a frequency of the oscillating output signal, generating a current output signal having a magnitude corresponding to the frequency of the oscillating output signal, and then comparing the current output signal to a reference signal to generate the feedback signal. The signal generating circuit may include an oscillator circuit responsive to a feedback signal and a frequency-to-current conversion circuit configured to generate a frequency dependent current signal that is compared to a reference current to generate an output signal corresponding to the frequency of the oscillating output signal. A feedback conversion circuit compares the output signal with a reference signal to generate the feedback signal to the oscillator circuit.
