Patent TW-432779-B (TW)
Title: Small-area and low-power low-frequency oscillator
Inventor: JANG WEI-SHIU
IPC: H03B11/08
Filed: 1999-11-03
Granted: 2001-05-01
Abstract: The present invention relates to a small-area and low-power low-frequency oscillator, which uses the difference of two current sources to charge and discharge a capacitor. The voltage output of the capacitor is connected to a trigger circuit. By suitably switching the charge and discharge switches, the circuit is continuously oscillated. Because the capacitor is charged and discharged by the current difference of the two current sources, the charge and discharge current can be designed to be very small to decrease the oscillation frequency thereby achieving the purpose of low frequency. In comparison with the conventional low-frequency oscillator that requires large resistor and large capacitor, or is achieved by using a frequency divider to divide a high frequency, the novel invention has the advantages of small area and low power, and thus is suitable for integrated circuit application.
