Frequency compensation circuit for adjusting internal oscillator frequency
A recently granted patent (Publication Number: US12003217B2) discloses a method, apparatus, and system for frequency compensation in electronic devices. The method involves determining a target calibration count of a fixed capacitor, identifying the current calibration count, and adjusting the frequency of an internal oscillator based on these counts. The apparatus includes a frequency compensation circuit, a fixed capacitor, and an internal oscillator, with the circuit adjusting the oscillator frequency based on the calibration counts. Similarly, the system comprises a processing device, fixed capacitor, internal oscillator, and frequency compensation circuit to perform the frequency adjustment based on calibration counts.
The innovation lies in the precise calibration of the fixed capacitor to ensure accurate frequency adjustments in electronic devices. By determining target calibration counts based on diode voltages and performing interpolations, the system can adjust the internal oscillator frequency effectively. The method, apparatus, and system provide a reliable mechanism for maintaining optimal performance by ensuring that the current calibration count meets the threshold criterion before adjusting the frequency. This technology can be beneficial in various electronic devices where precise frequency control is essential for proper functioning, highlighting its potential impact on improving overall device performance and reliability.
